Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Basis of Presentation The accompanying unaudited interim consolidated condensed financial statements include LCNB Corp. and its wholly-owned subsidiaries: LCNB National Bank and LCNB Risk Management, Inc., its captive insurance company. All material intercompany transactions and balances are eliminated in consolidation. The unaudited interim consolidated condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and the rules and regulations of the SEC. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, the unaudited interim consolidated financial statements include all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation of financial position, results of consolidated operations, and cash flows for the interim periods, as required by Regulation S-X, Rule 10-01. The consolidated condensed balance sheet as of December 31, 2020 has been derived from the audited consolidated balance sheet as of that date. The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements, accounting policies, and financial notes thereto included in LCNB's 2020 Annual Report on Form 10-K filed with the SEC.

Because LCNB does not have the intent to sell the investments and it is more likely than not that LCNB will not be required to sell the investments before recovery of their amortized cost bases, which may be at maturity, LCNB does not consider these investments to be other-than-temporarily impaired.

The excess of expected cash flows over the estimated fair value of acquired loans is recognized as interest income over the remaining contractual lives of the loans using the level yield method. Subsequent decreases in expected cash flows will require additions to the allowance for loan losses. Subsequent improvements in expected cash flows result in the recognition of additional interest income over the then-remaining contractual lives of the loans. Impaired loans acquired are accounted for under ASC 310-30. Factors considered in evaluating whether an acquired loan was impaired include delinquency status and history, updated borrower credit status, collateral information, and updated loan-to-value information. The difference between contractually required payments at the time of acquisition and the cash flows expected to be collected is referred to as the nonaccretable difference. The interest component of the cash flows expected to be collected is referred to as the accretable yield and is recognized as interest income over the remaining contractual life of the loan using the level yield method. Subsequent decreases in expected cash flows will require additions to the allowance for loan losses. Subsequent improvements in expected cash flows will result in a reclassification from the nonaccretable difference to the accretable yield. The following table provides at March 31, 2021 and December 31, 2020 the major classifications of acquired credit impaired loans that are accounted for in accordance with ASC 310-30 (in thousands): March 31, 2021 December 31, 2020 Acquired from First Capital Bancshares, Inc.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities LCNB is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit. They involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheets. Exposure to credit loss in the event of nonperformance by the other parties to financial instruments for commitments to extend credit is represented by the contract amount of those instruments. The Bounce Protection product, a customer deposit overdraft program, is offered as a service and does not constitute a contract between the customer and LCNB. LCNB uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. Financial instruments whose contract amounts represent off-balance-sheet credit risk at March 31, 2021 and December 31, 2020 were as follows (in thousands): March 31, 2021 December 31, 2020 Commitments to extend credit: Commercial loans $ 101,614 24,581 Other loans Fixed rate 14,534 14,668 Adjustable rate 3,743 4,386 Unused lines of credit: Fixed rate 28,440 24,205 Adjustable rate 134,773 133,073 Unused overdraft protection amounts on demand and NOW accounts 16,549 16,471 Standby letters of credit 55 243 Total commitments $ 299,708 217,627 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Unused lines of credit include amounts not drawn on line of credit loans. Commitments to extend credit and unused lines of credit generally have fixed expiration dates or other termination clauses. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. These guarantees generally are fully secured and have varying maturities. LCNB evaluates each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management's credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, residential realty, income-producing commercial property, agricultural property, and property, plant, and equipment. Capital expenditures include the construction or acquisition of new office buildings, improvements to LCNB's offices, purchases of furniture and equipment, and additions or improvements to LCNB's information technology system. Commitments outstanding for capital expenditures as of March 31, 2021 totaled approximately $1,840,000. Management believes that LCNB has sufficient liquidity to fund its lending and capital expenditure commitments. LCNB and its subsidiaries are parties to various claims and proceedings arising in the normal course of business. Management, after consultation with legal counsel, believes that the liabilities, if any, arising from such proceedings and claims will not be material to the consolidated financial position or results of operations.

Retirement Benefits [Abstract]
Retirement Plans	Retirement Plans LCNB participates in a noncontributory defined benefit multi-employer retirement plan that covers substantially all regular full-time employees hired before January 1, 2009. Employees hired before this date who received a benefit reduction under certain amendments to the defined benefit retirement plan receive an automatic contribution of 5% or 7% of their annual compensation, depending on the sum of an employee's age and vesting service, into their defined contribution plans (401(k) plans), regardless of the contributions made by the employees. These contributions are made annually and these employees do not receive any employer matches to their 401(k) contributions. Employees hired on or after January 1, 2009 receive a 50% employer match on their contributions into the 401(k) plan, up to a maximum LCNB contribution of 3% of each individual employee's annual compensation. Funding and administrative costs of the qualified noncontributory defined benefit retirement plan and 401(k) plan charged to pension and other employee benefits in the consolidated condensed statements of income for the three-month period ended March 31, 2021 and 2020 were as follows (in thousands): Three Months Ended 2021 2020 Qualified noncontributory defined benefit retirement plan $ 279 270 401(k) plan 160 165 Certain highly compensated former employees participate in a nonqualified defined benefit retirement plan. The nonqualified plan ensures that participants receive the full amount of benefits to which they would have been entitled under the noncontributory defined benefit retirement plan in the absence of limits on benefit levels imposed by certain sections of the Internal Revenue Code. This plan is limited to the original participants and no new participants have been added. The components of net periodic pension cost of the nonqualified defined benefit retirement plan for the three months ended March 31, 2021 and 2020 are summarized as follows (in thousands): Three Months Ended 2021 2020 Interest cost $ 13 16 Amortization of unrecognized net loss 2 — Net periodic pension cost $ 15 16 Amounts recognized in accumulated other comprehensive income, net of tax, at March 31, 2021 and December 31, 2020 for the nonqualified defined benefit retirement plan consists of (in thousands): March 31, 2021 December 31, 2020 Net actuarial loss $ 304 306 Past service cost — — Total recognized, net of tax $ 304 306

Stock Based Compensation	Stock Based Compensation LCNB established an Ownership Incentive Plan (the "2002 Plan") during 2002 that allowed for stock-based awards to eligible employees, as determined by the Board of Directors. The awards were made in the form of stock options, share awards, and/or appreciation rights. The 2002 Plan provided for the issuance of up to 200,000 shares of common stock. Options granted under the 2002 Plan vested ratably over a five The 2015 Ownership Incentive Plan (the "2015 Plan") was ratified by LCNB's shareholders at the annual meeting on April 28, 2015 and allows for stock-based awards to eligible employees, as determined by the Compensation Committee of the Board of Directors. Awards may be made in the form of stock options, appreciation rights, restricted shares, and/or restricted share units. The 2015 Plan provides for the issuance of up to 450,000 shares of common stock. The 2015 Plan will terminate on April 28, 2025 and is subject to earlier termination by the Compensation Committee. Stock-based awards may be in the form of treasury shares or newly issued shares. LCNB has not granted stock option awards since 2012.

Earnings Per Common Share

Earnings Per Common Share	3 Months Ended
	Mar. 31, 2021
Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings per Common Share LCNB has granted restricted stock awards with non-forfeitable dividend rights, which are considered participating securities. Accordingly, earnings per share is computed using the two-class method as required by ASC 260-10-45. Basic earnings per common share is calculated by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding during the period, which excludes the participating securities. Diluted earnings per common share is adjusted for the dilutive effects of stock options, warrants, and restricted stock. The diluted average number of common shares outstanding has been increased for the assumed exercise of stock options and warrants with proceeds used to purchase treasury shares at the average market price for the period. Earnings per share for the three months ended March 31, 2021 and 2020 were calculated as follows (dollars in thousands, except share and per share data): Three Months Ended 2021 2020 Net income $ 5,240 5,026 Less allocation of earnings and dividends to participating securities 18 11 Net income allocated to common shareholders $ 5,222 5,015 Weighted average common shares outstanding, gross 12,840,782 12,955,672 Less average participating securities 45,958 29,595 Weighted average number of shares outstanding used in the calculation of basic earnings per common share 12,794,824 12,926,077 Add dilutive effect of: Stock options 28 1,589 Adjusted weighted average number of shares outstanding used in the calculation of diluted earnings per common share 12,794,852 12,927,666 Earnings per common share: Basic $ 0.41 0.39 Diluted 0.41 0.39

Fair Value Measurements

Fair Value Measurements	3 Months Ended
	Mar. 31, 2021
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements LCNB measures certain assets at fair value using various valuation techniques and assumptions, depending on the nature of the asset. Fair value is defined as the price that would be received from the sale of an asset in an orderly transaction between market participants at the measurement date. The inputs to the valuation techniques used to measure fair value are assigned to one of three broad levels: • Level 1 – quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the reporting date. • Level 2 – inputs other than quoted prices included within level 1 that are observable for the asset or liability either directly or indirectly. Level 2 inputs may include quoted prices for similar assets in active markets, quoted prices for identical assets or liabilities in markets that are not active, inputs other than quoted prices (such as interest rates or yield curves) that are observable for the asset or liability, and inputs that are derived from or corroborated by observable market data. • Level 3 – inputs that are unobservable for the asset or liability. Equity Securities With a Readily Determinable Fair Value Equity securities with a readily determinable fair value are reported at fair value with changes in fair value reported in other operating income in the consolidated condensed statements of income. Fair values for equity securities are determined based on market quotations (level 1). LCNB has invested in two mutual funds that are traded in active markets and their fair values are based on market quotations (level 1). Investments in another two mutual funds are measured at fair value using net asset values ("NAV") and are considered level 1 because the NAVs are determined and published and are the basis for current transactions. Debt Securities, Available-for-Sale The majority of LCNB's financial debt securities are classified as available-for-sale. The securities are reported at fair value with unrealized holding gains and losses reported net of income taxes in accumulated other comprehensive income (loss). LCNB utilizes a pricing service for determining the fair values of its debt securities. Methods and significant assumptions used to estimate fair value were as follows: • Fair value for U.S. Treasury notes are determined based on market quotations (level 1). • Fair values for the other debt securities are calculated using the discounted cash flow method for each security. The discount rates for these cash flows are estimated by the pricing service using rates observed in the market (level 2). Cash flow streams are dependent on estimated prepayment speeds and the overall structure of the securities given existing market conditions. Assets Recorded at Fair Value on a Nonrecurring Basis Assets that may be recorded at fair value on a nonrecurring basis include impaired loans, other real estate owned, and other repossessed assets. A loan is considered impaired when management believes it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Impaired loans are carried at the present value of estimated future cash flows using the loan's existing rate or the fair value of collateral if the loan is collateral dependent, if this value is less than the loan balance. These inputs are considered to be level 3. The following table summarizes the valuation of LCNB's assets recorded at fair value by input levels as of March 31, 2021 and December 31, 2020 (in thousands): Fair Value Measurements at the End of Fair Value Measurements Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs Significant Unobservable Inputs March 31, 2021 Recurring fair value measurements: Equity securities with a readily determinable fair value: Equity securities $ 1,121 1,121 — — Mutual funds 52 52 — — Mutual funds measured at net asset value 1,333 1,333 — — Debt securities, available-for-sale: U.S. Treasury notes 16,216 16,216 — — U.S. Agency notes 75,137 — 75,137 — Corporate bonds 1,893 — 1,893 — U.S. Agency mortgage-backed securities 96,603 — 96,603 — Municipal securities: Non-taxable 12,433 — 12,433 — Taxable 35,337 — 35,337 — Total recurring fair value measurements $ 240,125 18,722 221,403 — Nonrecurring fair value measurements: Impaired loans $ 2,078 — — 2,078 Total nonrecurring fair value measurements $ 2,078 — — 2,078 December 31, 2020 Recurring fair value measurements: Equity securities with a readily determinable fair value: Equity securities $ 987 987 — — Mutual funds 50 50 — — Mutual funds measured at net asset value 1,352 1,352 — — Debt securities, available-for-sale: U.S. Treasury notes 2,388 2,388 — — U.S. Agency notes 67,900 — 67,900 — Corporate bonds 1,179 — 1,179 — U.S. Agency mortgage-backed securities 91,634 — 91,634 — Municipal securities: Non-taxable 12,933 — 12,933 — Taxable 33,437 — 33,437 — Total recurring fair value measurements $ 211,860 4,777 207,083 — Nonrecurring fair value measurements: Impaired loans $ 3,439 — — 3,439 Total nonrecurring fair value measurements $ 3,439 — — 3,439 The following table presents quantitative information about unobservable inputs used in nonrecurring level 3 fair value measurements at March 31, 2021 and December 31, 2020 (dollars in thousands): Range Fair Value Valuation Technique Unobservable Inputs High Low Weighted Average March 31, 2021 Impaired loans $ 2,078 Discounted cash flows Discount rate 8.25 % 4.00 % 4.72 % December 31, 2020 Impaired loans $ 1,352 Estimated sales price Adjustments for comparable properties, discounts to reflect current market conditions Not applicable 2,087 Discounted cash flows Discount rate 8.25 % 4.00 % 4.74 % Carrying amounts and estimated fair values of financial instruments as of March 31, 2021 and December 31, 2020 were as follows (in thousands): Fair Value Measurements at the End of Carrying Fair Quoted Significant Other Observable Inputs Significant Unobservable Inputs March 31, 2021 FINANCIAL ASSETS: Cash and cash equivalents $ 41,144 41,144 41,144 — — Debt securities, held-to-maturity 24,695 24,828 — — 24,828 Federal Reserve Bank stock 4,652 4,652 4,652 — — Federal Home Loan Bank stock 5,203 5,203 5,203 — — Loans, net 1,329,422 1,281,697 — — 1,281,697 Accrued interest receivable 8,665 8,665 — 8,665 — FINANCIAL LIABILITIES: Deposits 1,537,116 1,539,552 1,311,915 227,637 — Long-term debt 17,000 17,510 — 17,510 — Accrued interest payable 349 349 — 349 — December 31, 2020 FINANCIAL ASSETS: Cash and cash equivalents $ 31,730 31,730 31,730 — — Debt securities, held-to-maturity 24,810 24,960 — — 24,960 Federal Reserve Bank stock 4,652 4,652 4,652 — — Federal Home Loan Bank stock 5,203 5,203 5,203 — — Loans, net 1,293,693 1,252,642 — — 1,252,642 Accrued interest receivable 8,337 8,337 — 8,337 — FINANCIAL LIABILITIES: Deposits 1,455,423 1,458,413 1,212,903 245,510 — Long-term debt 22,000 22,595 — 22,595 — Accrued interest payable 452 452 — 452 — The fair values of off-balance-sheet financial instruments such as loan commitments and letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements. The fair values of such instruments were not material at March 31, 2021 and December 31, 2020. Fair values of financial instruments are based on various assumptions, including the discount rate and estimates of future cash flows. Therefore, the fair values presented may not represent amounts that could be realized in actual transactions. In addition, because the required disclosures exclude certain financial instruments and all nonfinancial instruments, any aggregation of the fair value amounts presented would not represent the underlying value of LCNB. The following methods and assumptions were used to estimate the fair value of certain financial instruments: Cash and cash equivalents The carrying amounts presented are deemed to approximate fair value. Equity securities without a readily determinable fair value Equity securities without a readily determinable fair value are measured at cost, less impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Debt securities, held-to-maturity Fair values for debt securities, held-to-maturity are based on quoted market prices for similar securities and/or discounted cash flow analysis or other methods. Federal Home Loan Bank stock and Federal Reserve Bank stock The carrying value of Federal Home Loan Bank and Federal Reserve Bank stock approximates fair value based on the respective redemptive provisions. Loans The estimated fair value of loans follows the guidance in ASU 2016-01, which prescribes an “exit price” approach in estimating and disclosing fair value of financial instruments. The fair value calculation discounts estimated future cash flows using rates that incorporated discounts for credit, liquidity, and marketability factors. Deposits The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities, which approximates market rates. Borrowings The carrying amounts of federal funds purchased, repurchase agreements, and U.S. Treasury demand note borrowings are deemed to approximate fair value of short-term borrowings. For long-term debt, fair values are estimated based on the discounted value of expected net cash flows using current interest rates. Accrued interest receivable and accrued interest payable Carrying amount approximates fair value.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements From time to time the FASB issues an ASU to communicate changes to U.S. generally accepted accounting principles. The following information provides brief summaries of newly issued but not yet effective ASUs that could have an effect on LCNB’s financial position or results of consolidated operations: ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ASU No. 2016-13 was issued in June 2016 and, once effective, will significantly change current guidance for recognizing impairment of financial instruments. Current guidance requires an "incurred loss" methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. ASU No. 2016-13 replaces the incurred loss impairment methodology with a new current expected credit loss ("CECL") methodology that reflects expected credit losses over the lives of the loans and requires consideration of a broader range of information to inform credit loss estimates. The ASU requires an organization to estimate all expected credit losses for financial assets measured at amortized cost, including loans and held-to-maturity debt securities, based on historical experience, current conditions, and reasonable and supportable forecasts. Additional disclosures are required. ASU No. 2016-13 also amends the accounting for credit losses on debt securities, available-for-sale, and purchased financial assets with credit deterioration. Under the new guidance, entities will determine whether all or a portion of the unrealized loss on an available-for-sale debt security is a credit loss. Any credit loss will be recognized as an allowance for credit losses on debt securities, available-for-sale, rather than as a direct reduction of the amortized cost basis of the investment, as is currently required. As a result, entities will recognize improvements to estimated credit losses on debt securities, available-for-sale, immediately in earnings rather than as interest income over time, as currently required. ASU No. 2016-13 eliminates the current accounting model for purchased credit impaired loans and debt securities. Instead, purchased financial assets with credit deterioration will be recorded gross of estimated credit losses as of the date of acquisition and the estimated credit losses amounts will be added to the allowance for credit losses. Thereafter, entities will account for additional impairment of such purchased assets using the models listed above. Originally, ASU No. 2016-13 would have taken effect for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. At their meeting on October 16, 2019, FASB approved a final ASU delaying the effective date for several major standards, including ASU No. 2016-13, if certain qualifications are met. The new effective date for SEC filers eligible to be smaller reporting companies ("SRC"), as defined, will be fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption is permitted. As an SRC, LCNB intends to adopt ASU No. 2016-13 for the fiscal year, and interim periods within the fiscal year, beginning after December 15, 2022. LCNB has created a cross-functional CECL Committee, which reports to the Audit Committee, composed of members from the lending, Wealth Management, and finance departments. During 2017, the CECL Committee selected a vendor to assist in implementation of and ongoing compliance with the new requirements. It has completed analyzing its data collection efforts, selected a calculation model, analyzed its pool segmentation and reporting mechanisms, and has finished back testing in preparation for adoption of the new methodology. While the committee and management expect that the implementation of ASU No. 2016-13 will increase the balance of the allowance for loan losses, they are continuing to evaluate the potential impact on LCNB's results of consolidated operations and financial position. The consolidated financial statement impact of this new standard cannot be reasonably estimated at this time.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements From time to time the FASB issues an ASU to communicate changes to U.S. generally accepted accounting principles. The following information provides brief summaries of newly issued but not yet effective ASUs that could have an effect on LCNB’s financial position or results of consolidated operations: ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ASU No. 2016-13 was issued in June 2016 and, once effective, will significantly change current guidance for recognizing impairment of financial instruments. Current guidance requires an "incurred loss" methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. ASU No. 2016-13 replaces the incurred loss impairment methodology with a new current expected credit loss ("CECL") methodology that reflects expected credit losses over the lives of the loans and requires consideration of a broader range of information to inform credit loss estimates. The ASU requires an organization to estimate all expected credit losses for financial assets measured at amortized cost, including loans and held-to-maturity debt securities, based on historical experience, current conditions, and reasonable and supportable forecasts. Additional disclosures are required. ASU No. 2016-13 also amends the accounting for credit losses on debt securities, available-for-sale, and purchased financial assets with credit deterioration. Under the new guidance, entities will determine whether all or a portion of the unrealized loss on an available-for-sale debt security is a credit loss. Any credit loss will be recognized as an allowance for credit losses on debt securities, available-for-sale, rather than as a direct reduction of the amortized cost basis of the investment, as is currently required. As a result, entities will recognize improvements to estimated credit losses on debt securities, available-for-sale, immediately in earnings rather than as interest income over time, as currently required. ASU No. 2016-13 eliminates the current accounting model for purchased credit impaired loans and debt securities. Instead, purchased financial assets with credit deterioration will be recorded gross of estimated credit losses as of the date of acquisition and the estimated credit losses amounts will be added to the allowance for credit losses. Thereafter, entities will account for additional impairment of such purchased assets using the models listed above. Originally, ASU No. 2016-13 would have taken effect for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.
