Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1 The consolidated financial statements include the accounts of American National Bankshares Inc. (the "Company") and its wholly owned subsidiary, American National Bank and Trust Company (the "Bank"). The Bank offers a wide variety of retail, commercial, secondary market mortgage lending, and trust and investment services which also include non-deposit products such as mutual funds and insurance policies. The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, goodwill and intangible assets, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, and the valuation of deferred tax assets and liabilities. The novel coronavirus (“COVID- 19” first 2020 March 2020, may may may may All significant inter-company transactions and accounts are eliminated in consolidation, with the exception of the AMNB Statutory Trust I and the MidCarolina Trusts, as detailed in Note 11.

The fair value of the loans was determined using market participant assumptions in estimating the amount and timing of both principal and interest cash flows expected to be collected on the loans and leases and then applying a market-based discount rate to those cash flows. In this regard, the acquired loans were segregated into pools based on loan type and credit risk. Loan type was determined based on collateral type, purpose, and lien position. Credit risk characteristics included risk rating groups (pass rated loans and adversely classified loans), and past due status. For valuation purposes, these pools were further disaggregated by maturity, pricing characteristics (e.g., fixed-rate, adjustable-rate) and re-payment structure (e.g., interest only, fully amortizing, balloon).

Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note 12 The Company uses derivative financial instruments ("derivatives") primarily to manage risks to the Company associated with changing interest rates. The Company's derivatives are hedging instruments in a qualifying hedge accounting relationship (cash flow or fair value hedge). The Company designates derivatives as cash flow hedges when they are used to manage exposure to variability in cash flows on variable rate borrowings such as the Company's trust preferred capital notes. The Company uses interest rate swap agreements as part of its hedging strategy by exchanging variable-rate interest payments on a notional amount equal to the principal amount of the borrowings for fixed-rate interest payments, with such interest rates set based on benchmarked interest rates. All interest rate swaps were entered into with counterparties that met the Company's credit standards and the agreements contain collateral provisions protecting the at-risk party. The Company believes that the credit risk inherent in these derivative contracts is not Terms and conditions of the interest rate swaps vary and amounts receivable or payable are recognized as accrued under the terms of the agreements. The Company assesses the effectiveness of each hedging relationship on a periodic basis.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	The consolidated financial statements include the accounts of American National Bankshares Inc. (the "Company") and its wholly owned subsidiary, American National Bank and Trust Company (the "Bank"). The Bank offers a wide variety of retail, commercial, secondary market mortgage lending, and trust and investment services which also include non-deposit products such as mutual funds and insurance policies. The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, goodwill and intangible assets, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, and the valuation of deferred tax assets and liabilities.
