Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation This quarterly report presents the consolidated financial statements of Lakeland Bancorp, Inc. and its subsidiaries, including Lakeland Bank (“Lakeland”) and Lakeland’s wholly owned subsidiaries (collectively, the “Company”). The accounting and reporting policies of the Company conform with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and predominant practices within the banking industry. The Company’s unaudited interim financial statements reflect all adjustments, such as normal recurring accruals that are, in the opinion of management, necessary for the fair presentation of the results of the interim periods. The results of operations for the six months ended June 30, 2019 do not necessarily indicate the results that the Company will achieve for all of 2019 . Certain information and footnote disclosures required under U.S. GAAP have been condensed or omitted, as permitted by rules and regulations of the Securities and Exchange Commission. These unaudited interim financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes that are presented in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications.

Acquisitions

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS On January 4, 2019, the Company completed its acquisition of Highlands Bancorp, Inc. ("Highlands"), a bank holding company headquartered in Vernon, New Jersey. Highlands was the parent of Highlands State Bank, which operated four branches in Sussex, Passaic and Morris Counties in New Jersey. This acquisition enabled the Company to broaden its presence in those counties. Effective as of the close of business on January 4, 2019 , Highlands merged into the Company and Highlands State Bank merged into Lakeland. Pursuant to the merger agreement, the shareholders of Highlands received for each outstanding share of Highlands common stock that they owned at the effective time of the merger, 1.015 shares of Lakeland Bancorp, Inc. common stock. The Company issued 2,837,524 shares of its common stock in the merger. Outstanding Highlands stock options were paid out in cash at the difference between $14.71 and an average strike price of $8.09 for a total cash payment of $797,000 . The acquisition was accounted for under the acquisition method of accounting and accordingly, the assets acquired and liabilities assumed in the acquisition were recorded at their estimated fair values as of the acquisition date. Highlands' assets were recorded at their preliminary estimated fair values as of January 4, 2019 and Highlands' results of operations will be included in the Company's Consolidated Statements of Income from that date forward. The assets acquired and liabilities assumed in the acquisition were recorded at their estimated fair values based on management's best estimates using information available at the date of the acquisition, including the use of a third-party valuation specialist. The fair values are preliminary estimates and subject to adjustment for up to one year after the closing date of the acquisition. During the quarter ended June 30, 2019, the Company revised the estimated fair value of the acquired assets as of the acquisition date as the result of additional information obtained. The adjustment related to credit-impaired loans acquired in the acquisition that were recorded at fair value and subsequently accounted for in accordance with Accounting Standards Codification ("ASC") Subtopic 310-30 and resulted in a $1.7 million increase in goodwill. The following table summarizes the estimated fair value of the acquired assets and liabilities assumed at the date of acquisition for Highlands. (in thousands) Cash and cash equivalents $ 13,454 Securities, available for sale 22,734 Federal Home Loan Bank stock 1,767 Loans held for sale 1,113 Loans 425,005 Premises and equipment 3,253 Goodwill 19,397 Identifiable intangible assets 3,728 Accrued interest receivable and other assets 6,051 Total assets acquired 496,502 Deposits (409,638 ) Other borrowings (27,800 ) Subordinated debt (13,157 ) Other liabilities (2,490 ) Total liabilities assumed (453,085 ) Net assets acquired $ 43,417 Loans acquired in the Highlands acquisition were recorded at fair value and subsequently accounted for in accordance with ASC Topic 310. There was no carryover related allowance for loan losses. The fair values of loans acquired from Highlands were estimated using cash flow projections based on the remaining maturity and repricing terms. Cash flows were adjusted for estimated future credit losses and the rate of prepayments. Projected cash flows were then discounted to present value using a risk-adjusted market rate for similar loans. The following is a summary of the credit impaired loans acquired in the Highlands acquisition as of the closing date and includes loans added during the second quarter of 2019. (in thousands) Contractually required principal and interest at acquisition $ 22,363 Contractual cash flows not expected to be collected (non-accretable difference) 7,129 Expected cash flows at acquisition $ 15,234 Interest component of expected cash flows (accretable difference) 1,431 Fair value of acquired loans $ 13,803 The core deposit intangible totaled $3.7 million and is being amortized over its estimated useful life of approximately ten years using an accelerated method. The goodwill will be evaluated annually for impairment. The goodwill is not deductible for tax purposes. The fair values of deposit liabilities with no stated maturities such as checking, money market and savings accounts, were assumed to equal the carrying amounts since these deposits are payable on demand. The fair values of certificates of deposits and IRAs represent the present value of contractual cash flows discounted at market rates for similar certificates of deposit. Direct costs related to the acquisition were expensed as incurred. During the three and six months ended June 30, 2019 , the Company incurred $318,000 and $3.2 million of merger and acquisition integration-related expenses, respectively, which have been separately stated in the Company's Consolidated Statements of Income. Supplemental Pro Forma Financial Information The following table provides unaudited condensed pro forma financial information assuming that the Highlands acquisition had been completed as of January 1, 2019, for the six months ended June 30, 2019 and as of January 1, 2018 for the six months ended June 30, 2018. The table below has been prepared for comparative purposes only and is not necessarily indicative of the actual results that would have been attained had the acquisitions occurred as of the beginning of the periods presented, nor is it indicative of future results. Furthermore, the unaudited pro forma information does not reflect management’s estimate of any revenue-enhancing opportunities nor anticipated cost savings or the impact of conforming certain accounting policies of the acquired companies to the Company’s policies that may have occurred as a result of the integration and consolidation of Highlands' operations. The pro forma information shown reflects adjustments related to certain purchase accounting fair value adjustments; amortization of core deposit and other intangibles; and related income tax effects. The Company has not provided separate information regarding revenue and earnings of Highlands since the acquisition because of the manner in which Highlands' branches and lending team were immediately merged into Lakeland’s branches and lending team making such information impracticable to provide.

Revenue Recognition	REVENUE RECOGNITION The Company’s primary source of revenue is interest income generated from loans and investment securities. Interest income is recognized according to the terms of the financial instrument agreement over the life of the loan or investment security unless it is determined that the counterparty is unable to continue making interest payments. Interest income also includes prepaid interest fees from commercial customers, which approximates the interest foregone on the balance of the loan prepaid. The Company’s additional source of income, also referred to as noninterest income, is generated from deposit related fees, interchange fees, loan fees, merchant fees, loan sales, investment services and other miscellaneous income and is largely based on contracts with customers. In these cases, the Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The Company considers a customer to be any party to which the Company will provide goods or services that are an output of the Company’s ordinary activities in exchange for consideration. There is little seasonality with regards to revenue from contracts with customers and all inter-company revenue is eliminated when the Company’s financial statements are consolidated. Generally, the Company enters into contracts with customers that are short-term in nature where the performance obligations are fulfilled and payment is processed at the same time. Such examples include revenue related to merchant fees, interchange fees and investment services income. In addition, revenue generated from existing customer relationships such as deposit accounts are also considered short-term in nature, because the relationship may be terminated at any time and payment is processed at the time performance obligations are fulfilled. As a result, the Company does not have contract assets, contract liabilities or related receivable accounts for contracts with customers. In cases where collectability is a concern, the Company does not record revenue. Generally, the pricing of transactions between the Company and each customer is either (i) established within a legally enforceable contract between the two parties, as is the case with the loan sales, or (ii) disclosed to the customer at a specific point in time, as is the case when a deposit account is opened or before a new loan is underwritten. Fees are usually fixed at a specific amount or as a percentage of a transaction amount. No judgment or estimates by management are required to record revenue related to these transactions and pricing is clearly identified within these contracts. The Company primarily operates in one geographic region, Northern and Central New Jersey and contiguous areas. Therefore, all significant operating decisions are based upon analysis of the Company as one operating segment or unit. We disaggregate our revenue from contracts with customers by contract-type and timing of revenue recognition, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Noninterest income not generated from customers during the Company’s ordinary activities primarily relates to mortgage servicing rights, gains/losses on the sale of investment securities, gains/losses on the sale of other real estate owned, gains/losses on the sale of property, plant and equipment, and income from bank owned life insurance. The following table sets forth the components of noninterest income for the three and six months ended June 30, 2019 and 2018 : For the Three Months Ended June 30, For the Six Months Ended June 30, (in thousands) 2019 2018 2019 2018 Deposit Related Fees and Charges Debit card interchange income $ 1,412 $ 1,277 $ 2,630 $ 2,395 Overdraft charges 981 900 1,977 2,009 ATM service charges 216 217 400 407 Demand deposit fees and charges 122 121 265 279 Savings service charges 24 30 56 66 Total 2,755 2,545 5,328 5,156 Commissions and Fees Loan fees 531 363 879 685 Wire transfer charges 305 274 572 522 Investment services income 427 311 779 539 Merchant fees 200 174 384 390 Commissions from sales of checks 111 112 214 220 Safe deposit income 90 104 181 188 Other income 60 65 121 128 Total 1,724 1,403 3,130 2,672 Gains on Sales of Loans 428 300 799 546 Other Income Gains on customer swap transactions 656 527 855 859 Title insurance income 29 73 119 122 Other income 67 58 128 155 Total 752 658 1,102 1,136 Revenue not from contracts with customers 730 803 1,753 1,533 Total Noninterest Income $ 6,389 $ 5,709 $ 12,112 $ 11,043 Timing of Revenue Recognition Products and services transferred at a point in time 5,641 4,888 10,322 9,473 Products and services transferred over time 18 18 37 37 Revenue not from contracts with customers 730 803 1,753 1,533 Total Noninterest Income $ 6,389 $ 5,709 $ 12,112 $ 11,043

Fair value below cost is solely due to interest rate movements and is deemed temporary. Investment securities, including the mortgage-backed securities and corporate securities, are evaluated on a periodic basis to determine if factors are identified that would require further analysis. In evaluating the Company’s securities, management considers the following items: • The Company’s ability and intent to hold the securities, including an evaluation of the need to sell the security to meet certain liquidity measures, or whether the Company has sufficient levels of cash to hold the identified security in order to recover the entire amortized cost of the security; • The financial condition of the underlying issuer; • The credit ratings of the underlying issuer and if any changes in the credit rating have occurred; • The length of time the security’s fair value has been less than amortized cost; and • Adverse conditions related to the security or its issuer if the issuer has failed to make scheduled payments or other factors. If the above factors indicate that an additional analysis is required, management will perform a discounted cash flow analysis evaluating the security. Equity securities at fair value The Company has an equity securities portfolio which consists of investments in other financial institutions for market appreciation purposes and investments in Community Reinvestment funds. The market value of these investments was $15.4 million and $15.9 million at June 30, 2019 and December 31, 2018 , respectively. Upon implementation of Accounting Standards Update 2016-01 - Financial Instruments ("ASU 2016-01"), the Company made a cumulative adjustment of $2.0 million from other comprehensive income to retained earnings as of January 1, 2018. For the six months ended June 30, 2019 , the Company recorded proceeds from sales of equity securities of $1.2 million and recorded sales of $1.7 million for the six months ended June 30, 2018 . The Company recorded $453,000 and $55,000 in market value gains on equity securities in noninterest income for the six months ended June 30, 2019 and 2018 , respectively. As of June 30, 2019 , the market value of equity investments in other financial institutions was $1.8 million . The market value of the Community Reinvestment funds at June 30, 2019 was $13.6 million and includes $3.5 million that are primarily invested in community development loans that are guaranteed by the Small Business Administration (“SBA”). Because the funds are primarily guaranteed by the federal government there are minimal changes in market value between accounting periods. These funds can be redeemed with 60 days notice at the net asset value less unpaid management fees with the approval of the fund manager. As of June 30, 2019 , the net amortized cost equaled the market value of the investment. There are no unfunded commitments related to these investments. The Community Reinvestment funds include $10.1 million that are primarily invested in government guaranteed loans, mortgage-backed securities, small business loans and other instruments supporting affordable housing and economic development. The Company may redeem these funds at the net asset value calculated at the end of the current business day less any unpaid management fees. There are no restrictions on redemptions for the holdings in these investments other than the notice required by the fund manager. There are no unfunded commitments related to these investments.

Interest that would have been accrued on impaired loans during the first six months of 2019 and 2018 had the loans been performing under original terms would have been $500,000 and $566,000 , respectively. Credit Quality Indicators The class of loans is determined by internal risk rating. Management closely and continually monitors the quality of its loans and assesses the quantitative and qualitative risks arising from the credit quality of its loans. Lakeland assigns a credit risk rating to all commercial loans and loan commitments. The credit risk rating system has been developed by management to provide a methodology to be used by loan officers, department heads and senior management in identifying various levels of credit risk that exist within Lakeland’s commercial loan portfolios. The risk rating system assists senior management in evaluating Lakeland’s commercial loan portfolio, analyzing trends, and determining the proper level of required reserves to be recommended to the Board. In assigning risk ratings, management considers, among other things, a borrower’s debt service coverage, earnings strength, loan to value ratios, guarantor support, industry conditions and economic conditions.

Troubled Debt Restructurings Loans are classified as troubled debt restructured loans in cases where borrowers experience financial difficulties and Lakeland makes certain concessionary modifications to contractual terms. Restructured loans typically involve a modification of terms such as a reduction of the stated interest rate, a moratorium of principal payments and/or an extension of the maturity date at a stated interest rate lower than the current market rate of a new loan with similar risk. The Company considers the potential losses on these loans as well as the remainder of its impaired loans while considering the adequacy of the allowance for loan losses. The following table summarizes loans that have been restructured during the three and six months ended June 30, 2019 and 2018 : For the Three Months Ended June 30, 2019 For the Three Months Ended June 30, 2018 (dollars in thousands) Number of Contracts Pre- Modification Outstanding Recorded Investment Post- Modification Outstanding Recorded Investment Number of Contracts Pre- Modification Outstanding Recorded Investment Post- Modification Outstanding Recorded Investment Commercial, secured by real estate — $ — $ — 1 $ 170 $ 170 Commercial, industrial and other — — — 1 950 950 — $ — $ — 2 $ 1,120 $ 1,120 For the Six Months Ended June 30, 2019 For the Six Months Ended June 30, 2018 (dollars in thousands) Number of Contracts Pre- Modification Outstanding Recorded Investment Post- Modification Outstanding Recorded Investment Number of Contracts Pre- Modification Outstanding Recorded Investment Post- Modification Outstanding Recorded Investment Commercial, secured by real estate — $ — $ — 3 $ 1,827 $ 1,827 Commercial, industrial and other — — — 1 950 950 — $ — $ — 4 $ 2,777 $ 2,777 The following table summarizes as of June 30, 2019 and 2018 , loans that were restructured within the previous twelve months that have subsequently defaulted: June 30, 2019 June 30, 2018 (dollars in thousands) Number of Recorded Number of Recorded Commercial, secured by real estate — $ — 2 $ 1,234 Commercial, industrial and other — — 1 950 Equipment financing — — 1 11 — $ — 4 $ 2,195 Other Real Estate and Other Repossessed Assets At June 30, 2019 and December 31, 2018 , the Company had other real estate owned of $532,000 and $830,000 , respectively.

Leases [Abstract]
Leases	LEASES The Company leases certain premises and equipment under operating leases. Portions of certain properties are subleased for terms extending through 2024. At June 30, 2019 , the Company had lease liabilities totaling $20.2 million and right-of-use assets totaling $18.6 million related to these leases. The calculated amount of the right-of-use asset and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of the minimum lease payments. The Company's lease agreements often include one or more options to renew at the Company's discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the right-of-use asset and lease liability. The Company uses its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. For the six months ended June 30, 2019 , the weighted average remaining lease term for operating leases was 10.96 years and the weighted average discount rate used in the measurement of operating lease liabilities was 3.50% . As the Company elected not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance and utilities. Lease costs were as follows: (in thousands) Three Months Ended Six Months Ended June 30, 2019 Operating lease cost $ 826 $ 1,646 Short-term lease cost — — Variable lease cost 33 68 Sublease income (30 ) (61 ) Net lease cost $ 829 $ 1,653 Rent expense for the three and six months ended June 30, 2018 , prior to the adoption of ASU 2016-02, was $737,000 and $1.5 million , respectively. Other information (in thousands) Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 1,310 Right-of-use asset obtained in exchange for new operating lease liabilities $ 765 There were no sale and leaseback transactions, leveraged leases or lease transactions with related parties during the three and six months ended June 30, 2019 . At June 30, 2019 , the Company had no leases that had not yet commenced. A maturity analysis of operating lease liabilities and reconciliation of the undiscounted cash flows to the total operating lease liability at June 30, 2019 is as follows: (in thousands) Within one year $ 3,227 After one year but within two years 3,004 After two year but within three years 2,664 After three year but within four years 2,168 After four year but within five years 2,063 After 5 years 11,546 Total undiscounted cash flows 24,672 Discount on cash flows (4,497 ) Total lease liability $ 20,175

Derivatives

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	DERIVATIVES Lakeland is a party to interest rate derivatives that are not designated as hedging instruments. Under a program, Lakeland executes interest rate swaps with commercial lending customers to facilitate their respective risk management strategies. These interest rate swaps with customers are simultaneously offset by interest rate swaps that Lakeland executes with a third party, such that Lakeland minimizes its net risk exposure resulting from such transactions. Because the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The changes in the fair value of the swaps offset each other, except for the credit risk of the counterparties, which is determined by taking into consideration the risk rating, probability of default and loss given default for all counterparties. Lakeland had $23.5 million and $498,000 , respectively, in available for sale securities pledged for collateral on its interest rate swaps with the financial institution for June 30, 2019 and December 31, 2018 . In June 2016, the Company entered into two cash flow hedges in order to hedge the variable cash outflows associated with its subordinated debentures. The notional value of these hedges was $30.0 million . The Company’s objectives in using cash flow hedges are to add stability to interest expense and to manage its exposure to interest rate movements. The Company used interest rate swaps designated as cash flow hedges which involved the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. In these particular hedges the Company is paying a third party an average of 1.10% in exchange for a payment at 3 month LIBOR . The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the six months ended June 30, 2019 , the Company did not record any hedge ineffectiveness. The Company recognized $238,000 and $132,000 of accumulated other comprehensive income that was reclassified into interest expense for the first six months of 2019 and 2018 , respectively. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s debt. During the next twelve months, the Company estimates that $314,000 will be reclassified as a decrease to interest expense should the rate environment remain the same. The following table presents summary information regarding these derivatives for the periods presented (dollars in thousands): June 30, 2019 Notional Amount Average Maturity (Years) Weighted Average Fixed Rate Weighted Average Variable Rate Fair Value Classified in Other Assets: 3rd Party interest rate swaps $ 38,141 7.0 3.72 % 1 Mo.

Fair Value Disclosures [Abstract]
Estimated Fair Value of Financial Instruments and Fair Value Measurement	ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENT Fair Value Measurement Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels giving the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest level priority to unobservable inputs (level 3 measurements). The following describes the three levels of fair value hierarchy: Level 1 – unadjusted quoted prices in active markets for identical assets or liabilities; includes U.S. Treasury Notes, and other U.S. Government Agency securities that actively trade in over-the-counter markets; equity securities and mutual funds that actively trade in over-the-counter markets. Level 2 – quoted prices for similar assets or liabilities in active markets; or quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs other than quoted prices that are observable for the asset or liability including yield curves, volatilities, and prepayment speeds. Level 3 – unobservable inputs for the asset or liability that reflect the Company’s own assumptions about assumptions that market participants would use in the pricing of the asset or liability and that are consequently not based on market activity but upon particular valuation techniques. The Company’s assets that are measured at fair value on a recurring basis are its available for sale investment securities and its interest rate swaps. The Company obtains fair values on its securities using information from a third-party servicer. If quoted prices for securities are available in an active market, those securities are classified as Level 1 securities. The Company has U.S. Treasury Notes and certain equity securities that are classified as Level 1 securities. Level 2 securities were primarily comprised of U.S. Agency bonds, residential mortgage-backed securities, obligations of state and political subdivisions and corporate securities. Fair values were estimated primarily by obtaining quoted prices for similar assets in active markets or through the use of pricing models supported with market data information. Standard inputs include benchmark yields, reported trades, broker-dealer quotes, issuer spreads, bids and offers. On a quarterly basis, the Company reviews the pricing information received from the Company’s third-party pricing service. This review includes a comparison to non-binding third-party quotes. The fair values of derivatives are based on valuation models from a third party using current market terms (including interest rates and fees), the remaining terms of the agreements and the credit worthiness of the counter party as of the measurement date (Level 2). The following table sets forth the Company’s financial assets that were accounted for at fair value on a recurring basis as of the periods presented by level within the fair value hierarchy. During the six months ended June 30, 2019 , the Company did not make any transfers between any levels within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement: (in thousands) Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value June 30, 2019 Assets: Investment securities, available for sale U.S. Treasury and government agencies $ 16,525 $ 123,345 $ — $ 139,870 Mortgage-backed securities — 473,786 — 473,786 Obligations of states and political subdivisions — 45,343 — 45,343 Debt securities — 5,123 — 5,123 Total securities available for sale 16,525 647,597 — 664,122 Equity securities, at fair value 1,806 13,576 — 15,382 Derivative assets — 23,372 — 23,372 Total Assets $ 18,331 $ 684,545 $ — $ 702,876 Liabilities: Derivative liabilities $ — $ 22,969 $ — $ 22,969 Total Liabilities $ — $ 22,969 $ — $ 22,969 December 31, 2018 Assets: Investment securities, available for sale U.S. Treasury and government agencies $ 4,920 $ 136,007 $ — $ 140,927 Mortgage-backed securities — 447,094 — 447,094 Obligations of states and political subdivisions — 45,505 — 45,505 Debt securities — 5,092 — 5,092 Total securities available for sale 4,920 633,698 — 638,618 Equity securities, at fair value 2,731 13,190 — 15,921 Derivative assets — 12,135 — 12,135 Total Assets $ 7,651 $ 659,023 $ — $ 666,674 Liabilities: Derivative liabilities $ — $ 11,036 $ — $ 11,036 Total Liabilities $ — $ 11,036 $ — $ 11,036 The following table sets forth the Company’s assets subject to fair value adjustments (impairment) on a non-recurring basis. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement: (in thousands) (Level 1) (Level 2) (Level 3) Total Fair Value June 30, 2019 Assets: Impaired loans $ — $ — $ 17,385 $ 17,385 Loans held for sale — 1,391 — 1,391 Other real estate owned and other repossessed assets — — 532 532 December 31, 2018 Assets: Impaired loans $ — $ — $ 19,702 $ 19,702 Loans held for sale — 1,113 — 1,113 Other real estate owned and other repossessed assets — — 830 830 Impaired loans are evaluated and valued at the time the loan is identified as impaired at the lower of cost or market value. Because most of Lakeland’s impaired loans are collateral dependent, fair value is generally measured based on the value of the collateral, less estimated costs to sell, securing these loans and is classified at a level 3 in the fair value hierarchy. Collateral may be real estate, accounts receivable, inventory, equipment and/or other business assets. The value of real estate is assessed based on appraisals by qualified third-party licensed appraisers. The appraisers may use the income approach to value the collateral using discount rates (with ranges of 5 - 11% ) or capitalization rates (with ranges of 4 - 9% ) to evaluate the property. The value of the equipment may be determined by an appraiser, if significant, inquiry through a recognized valuation resource, or by the value on the borrower’s financial statements. Field examiner reviews on business assets may be conducted based on the loan exposure and reliance on this type of collateral. Appraised and reported values may be adjusted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and client’s business. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors identified above. The Company has a held for sale loan portfolio that consists of residential mortgages that are being sold in the secondary market. The Company records these mortgages at the lower of cost or market value. Fair value is generally determined by the value of purchase commitments. Other real estate owned (“OREO”) and other repossessed assets, representing property acquired through foreclosure or deed in lieu of foreclosure, are carried at fair value less estimated disposal costs of the acquired property. Fair value on other real estate owned is based on the appraised value of the collateral using discount rates or capitalization rates similar to those used in impaired loan valuation. The fair value of other repossessed assets is estimated by inquiry through recognized valuation resources. Changes in the assumptions or methodologies used to estimate fair values may materially affect the estimated amounts. Changes in economic conditions, locally or nationally, could impact the value of the estimated amounts of impaired loans, OREO and other repossessed assets. Fair Value of Certain Financial Instruments Estimated fair values have been determined by the Company using the best available data and an estimation methodology suitable for each category of financial instruments. Management is concerned that there may not be reasonable comparability between institutions due to the wide range of permitted assumptions and methodologies in the absence of active markets. This lack of uniformity gives rise to a high degree of subjectivity in estimating financial instrument fair values. The estimation methodologies used, the estimated fair values and recorded book balances at June 30, 2019 , and December 31, 2018 , are outlined below. This summary, as well as the table below, excludes financial assets and liabilities for which carrying value approximates fair value. For financial assets, these include cash and cash equivalents. For financial liabilities, these include noninterest-bearing demand deposits, savings and interest-bearing transaction accounts and federal funds purchased and securities sold under agreements to repurchase. The estimated fair value of demand, savings and interest-bearing transaction accounts is the amount payable on demand at the reporting date. Carrying value is used because there is no stated maturity on these accounts, and the customer has the ability to withdraw the funds immediately. Also excluded from this summary and the following table are those financial instruments recorded at fair value on a recurring basis, as previously described. The fair value of investment securities held to maturity was measured using information from the same third-party servicer used for investment securities available for sale using the same methodologies discussed above. Investment securities held to maturity includes $2.9 million in short-term municipal bond anticipation notes and $2.5 million in subordinated debt that are non-rated and do not have an active secondary market or information readily available on standard financial systems. As a result, the securities are classified as Level 3 securities. Management performs a credit analysis before investing in these securities. FHLB stock is an equity interest that can be sold to the issuing FHLB, to other Federal Home Loan Banks, or to other member banks at its par value. Because ownership of these securities is restricted, they do not have a readily determinable fair value. As such, the Company’s FHLB stock is recorded at cost or par value and is evaluated for impairment each reporting period by considering the ultimate recoverability of the investment rather than temporary declines in value. The Company’s evaluation primarily includes an evaluation of liquidity, capitalization, operating performance, commitments, and regulatory or legislative events. The net loan portfolio has been valued using an exit price approach, which incorporates a buildup discount rate calculation that uses a swap rate adjusted for credit risk, servicing costs, a liquidity premium and a prepayment premium. For fixed maturity certificates of deposit, fair value is estimated based on the present value of discounted cash flows using the rates currently offered for deposits of similar remaining maturities. The carrying amount of accrued interest payable approximates its fair value. The fair value of long-term debt is based upon the discounted value of contractual cash flows. The Company estimates the discount rate using the rates currently offered for similar borrowing arrangements. The fair value of subordinated debentures is based on bid/ask prices from brokers for similar types of instruments. The fair values of commitments to extend credit and standby letters of credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of guarantees and letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date. The fair value of commitments to extend credit and standby letters of credit are deemed immaterial. The following table presents the carrying values, fair values and placement in the fair value hierarchy of the Company’s financial instruments as of June 30, 2019 and December 31, 2018 : (in thousands) Carrying Value Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) June 30, 2019 Financial Assets: Investment securities held to maturity $ 160,328 $ 161,028 $ — $ 155,624 $ 5,404 Federal Home Loan Bank and other membership bank stocks 23,642 23,642 — 23,642 — Loans, net 4,883,711 4,936,965 — — 4,936,965 Financial Liabilities: Certificates of deposit 985,340 984,991 — 984,991 — Other borrowings 175,820 175,998 — 175,998 — Subordinated debentures 118,202 116,139 — — 116,139 December 31, 2018 Financial Assets: Investment securities held to maturity $ 153,646 $ 150,932 $ — $ 143,913 $ 7,019 Federal Home Loan Bank and other membership bank stocks 13,301 13,301 — 13,301 — Loans, net 4,419,045 4,341,477 — — 4,341,477 Financial Liabilities: Certificates of deposit 757,038 750,801 — 750,801 — Other borrowings 181,118 176,921 — 176,921 — Subordinated debentures 105,027 102,497 — — 102,497

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS In August 2018, the Financial Accounting Standards Board ("FASB") issued Update 2018-13, an update to Topic 820, Fair Value Measurement, to improve the effectiveness of fair value measurement disclosures. Among other provisions, the update removes requirements to disclose amounts and reasons of transfers between Level 1 and Level 2 in the fair value hierarchy, and it modifies the disclosures regarding transfers in and out of Level 3 of the fair value hierarchy. The update requires a discussion regarding the change in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This update will be effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2019. Because the Company does not typically have Level 3 fair value measurements, the update is not expected to have a material impact on the Company's financial statements. In August 2018, the FASB issued Update 2018-15, an update to Subtopic 350-40, Intangibles - Goodwill and Other - Internal-Use Software, which aligns the requirements for capitalizing implementation costs in a cloud-computing arrangement service contract with the requirements for capitalizing implementation costs incurred for an internal-use software license. Implementation costs incurred by customers in a cloud computing arrangement are to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance. This update will be effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2019. The Company is currently assessing the impact that the guidance will have on its financial statements. In August 2018, the FASB issued Update 2018-14, an update to Subtopic 715-20, Compensation - Retirement Benefits - Defined Benefit Plans - General, which changes the disclosure of accounting and reporting requirements related to single-employer defined benefit pension or other postretirement benefit plans. The amendments in the update remove disclosures that are no longer considered cost-beneficial, clarify the specific requirements of disclosures and add disclosure requirements identified as relevant. For calendar-year public companies, the changes will be effective for annual periods, including interim periods within those annual periods, in 2020. Because the Company has minimal pension plans that require calculation of projected benefit obligations or accumulated benefit obligations, the update will not have a material impact on the Company's financial statements. In June 2018, the FASB issued Update 2018-07, an update to Topic 718, Compensation - Stock Compensation, expanding earlier guidance on stock compensation to include share-based payments issued to nonemployees for goods and services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially the same. This update will be effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2018. Earlier adoption was permitted. The adoption of this update did not have a significant impact on the Company's financial statements. In August 2017, the FASB issued Update 2017-05, an update to Subtopic 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets, intended to improve and simplify accounting rules around hedge accounting. Amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments in this update also make certain targeted improvements to simplify the application of hedge accounting guidance and ease the administrative burden of hedge documentation requirements and assessing hedge effectiveness. This update will be effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2019. The Company is still evaluating the impact that this guidance will have on its financial statements. In July 2017, the FASB issued Update 2017-11, guidance which simplifies the accounting for certain financial instruments with down round features, a provision in an equity-linked financial instrument (or embedded feature) that provides a downward adjustment of the current exercise price based on the price of future equity offerings. The provisions of the new guidance related to down rounds are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of this update did not have a material impact on the Company’s financial statements because the Company does not have any equity-linked financial instruments that have such down round features. In March 2017, the FASB issued Update 2017-08, an update to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs, which shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. Under current GAAP, entities amortize the premium as an adjustment of yield over the contractual life of the instrument even if the holder is certain that the call will be exercised. As a result, upon the exercise of a call on a callable debt security held at a premium, the unamortized premium is recorded as a loss in earnings. The update shortens the amortization period for certain callable debt securities held at a premium and requires the premium be amortized to the earliest call date. This update will be effective for annual and interim periods beginning after December 15, 2018. Entities are required to apply the amendments on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The adoption of this update did not have a material impact on the Company’s financial statements. In January 2017, the FASB issued Update 2017-04, an update to Topic 350, Intangibles - Goodwill and Other, to simplify the test for goodwill impairment. This amendment eliminates Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. This update will be effective for the Company’s financial statements for annual years beginning after December 15, 2019. The adoption of this update is not expected to have a material impact on the Company’s financial statements. In June 2016, the FASB issued Update 2016-13, Topic 326, Financial Instruments - Credit Losses, an accounting standards update pertaining to the measurement of credit losses on financial instruments. This update requires the measurement of all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. This update is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. This update will be effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2019. The Company formed a working group under the direction of the Chief Risk Officer that is comprised of individuals from the credit, risk management, finance and project management areas for implementation of this update. In 2018, the Company contracted with a software and advisory service provider to aid in implementation. The software provider has completed configuration of the software platform and the Company has completed initial data preparation for the software. The Company and software provider have begun evaluating results of initial scenario analysis and as a result have been reviewing and fine tuning assumptions in the model. The Company is still developing qualitative adjustments, as well as metrics for determination of a reasonable and supportable forecast period, and the Company has engaged a third-party firm to conduct a review and validation of its methodology and models. The Company is also developing its future process and governance structure to prepare for production parallel in the second half of 2019 to ensure Lakeland is prepared for adoption of the standard as of January 1, 2020. The adoption of this standard could have a material impact on the Company’s financial statements depending on the characteristics of the loan portfolio, as well as the current and forecasted economic conditions as of the date of adoption. The Company is currently in the process of evaluating the quantitative and qualitative effects of the standard on its estimated credit losses under the standard. In February 2016, FASB issued Update 2016-02, Topic 842, Leases, accounting guidance that requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. Lessor accounting remains largely unchanged under the new guidance. The guidance is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that reporting period, with early adoption permitted. A modified retrospective approach must be applied for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company retained the services of a software provider to aid in its implementation. In the third quarter of 2018, the FASB issued updates which included targeted improvements to the leasing guidance that is intended to reduce costs and ease implementation of the leases standard. The improvements include an optional transition method to adopt the new leases standard where the entity could initially apply the new leases standard at the adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity's reporting for comparative periods presented in the financial statements in which it adopts the new leases standard, will continue to be in accordance with Accounting Standards Codification ("ASC") Topic 840, Leases. An entity that adopts this additional transition method, must provide the required disclosures for all periods that continue to be in accordance with the current ASC 840. The lease update also includes a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease component and, instead, to account for these components as a single component if the nonlease components otherwise would be accounted for under the new revenue guidance and both of the following conditions are met: 1) the timing and pattern of transfer of the nonlease component(s) and associated lease component are the same, and 2) the lease component, if accounted for separately, would be classified as an operating lease. Management used the optional transition method discussed above and also used the practical expedient to account for non-lease components with the associated lease component as a single component assuming the appropriate conditions are met. The FASB issued further clarification of the standard and addressed implementation and disclosure requirements. With the adoption of this update, the Company recorded an operating lease right-of-use asset of $18.7 million , a corresponding liability of $20.2 million and a cumulative adjustment to retained earnings of $125,000 .

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation This quarterly report presents the consolidated financial statements of Lakeland Bancorp, Inc. and its subsidiaries, including Lakeland Bank (“Lakeland”) and Lakeland’s wholly owned subsidiaries (collectively, the “Company”). The accounting and reporting policies of the Company conform with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and predominant practices within the banking industry. The Company’s unaudited interim financial statements reflect all adjustments, such as normal recurring accruals that are, in the opinion of management, necessary for the fair presentation of the results of the interim periods. The results of operations for the six months ended June 30, 2019 do not necessarily indicate the results that the Company will achieve for all of 2019 . Certain information and footnote disclosures required under U.S. GAAP have been condensed or omitted, as permitted by rules and regulations of the Securities and Exchange Commission. These unaudited interim financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes that are presented in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications.

The adoption of this update did not have a significant impact on the Company's financial statements. In August 2017, the FASB issued Update 2017-05, an update to Subtopic 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets, intended to improve and simplify accounting rules around hedge accounting. Amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments in this update also make certain targeted improvements to simplify the application of hedge accounting guidance and ease the administrative burden of hedge documentation requirements and assessing hedge effectiveness. This update will be effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2019. The Company is still evaluating the impact that this guidance will have on its financial statements. In July 2017, the FASB issued Update 2017-11, guidance which simplifies the accounting for certain financial instruments with down round features, a provision in an equity-linked financial instrument (or embedded feature) that provides a downward adjustment of the current exercise price based on the price of future equity offerings. The provisions of the new guidance related to down rounds are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of this update did not have a material impact on the Company’s financial statements because the Company does not have any equity-linked financial instruments that have such down round features. In March 2017, the FASB issued Update 2017-08, an update to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs, which shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. Under current GAAP, entities amortize the premium as an adjustment of yield over the contractual life of the instrument even if the holder is certain that the call will be exercised. As a result, upon the exercise of a call on a callable debt security held at a premium, the unamortized premium is recorded as a loss in earnings. The update shortens the amortization period for certain callable debt securities held at a premium and requires the premium be amortized to the earliest call date. This update will be effective for annual and interim periods beginning after December 15, 2018. Entities are required to apply the amendments on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The adoption of this update did not have a material impact on the Company’s financial statements. In January 2017, the FASB issued Update 2017-04, an update to Topic 350, Intangibles - Goodwill and Other, to simplify the test for goodwill impairment. This amendment eliminates Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. This update will be effective for the Company’s financial statements for annual years beginning after December 15, 2019. The adoption of this update is not expected to have a material impact on the Company’s financial statements. In June 2016, the FASB issued Update 2016-13, Topic 326, Financial Instruments - Credit Losses, an accounting standards update pertaining to the measurement of credit losses on financial instruments. This update requires the measurement of all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. This update is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. This update will be effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2019. The Company formed a working group under the direction of the Chief Risk Officer that is comprised of individuals from the credit, risk management, finance and project management areas for implementation of this update. In 2018, the Company contracted with a software and advisory service provider to aid in implementation. The software provider has completed configuration of the software platform and the Company has completed initial data preparation for the software. The Company and software provider have begun evaluating results of initial scenario analysis and as a result have been reviewing and fine tuning assumptions in the model. The Company is still developing qualitative adjustments, as well as metrics for determination of a reasonable and supportable forecast period, and the Company has engaged a third-party firm to conduct a review and validation of its methodology and models. The Company is also developing its future process and governance structure to prepare for production parallel in the second half of 2019 to ensure Lakeland is prepared for adoption of the standard as of January 1, 2020. The adoption of this standard could have a material impact on the Company’s financial statements depending on the characteristics of the loan portfolio, as well as the current and forecasted economic conditions as of the date of adoption. The Company is currently in the process of evaluating the quantitative and qualitative effects of the standard on its estimated credit losses under the standard. In February 2016, FASB issued Update 2016-02, Topic 842, Leases, accounting guidance that requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. Lessor accounting remains largely unchanged under the new guidance. The guidance is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that reporting period, with early adoption permitted. A modified retrospective approach must be applied for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company retained the services of a software provider to aid in its implementation. In the third quarter of 2018, the FASB issued updates which included targeted improvements to the leasing guidance that is intended to reduce costs and ease implementation of the leases standard. The improvements include an optional transition method to adopt the new leases standard where the entity could initially apply the new leases standard at the adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity's reporting for comparative periods presented in the financial statements in which it adopts the new leases standard, will continue to be in accordance with Accounting Standards Codification ("ASC") Topic 840, Leases. An entity that adopts this additional transition method, must provide the required disclosures for all periods that continue to be in accordance with the current ASC 840. The lease update also includes a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease component and, instead, to account for these components as a single component if the nonlease components otherwise would be accounted for under the new revenue guidance and both of the following conditions are met: 1) the timing and pattern of transfer of the nonlease component(s) and associated lease component are the same, and 2) the lease component, if accounted for separately, would be classified as an operating lease. Management used the optional transition method discussed above and also used the practical expedient to account for non-lease components with the associated lease component as a single component assuming the appropriate conditions are met. The FASB issued further clarification of the standard and addressed implementation and disclosure requirements. With the adoption of this update, the Company recorded an operating lease right-of-use asset of $18.7 million , a corresponding liability of $20.2 million and a cumulative adjustment to retained earnings of $125,000 .
