Notes to Financial Statements
Significant Accounting Policies [Text Block]	Note 1 The consolidated financial statements include the accounts of American National Bankshares Inc. (NASDAQ: AMNB) (the "Company") and its wholly-owned subsidiary, American National Bank and Trust Company (the "Bank"). The Company is a multi-state bank holding company headquartered in Danville, Virginia. The Bank is a community bank organization serving Virginia and North Carolina with 26 banking offices. In addition to traditional retail, commercial and mortgage offerings, the Bank also provides trust and investment services through its Trust and Investment Services Division. 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.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note 9 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.

Basis of Accounting, Policy [Policy Text Block]	The consolidated financial statements include the accounts of American National Bankshares Inc. (NASDAQ: AMNB) (the "Company") and its wholly-owned subsidiary, American National Bank and Trust Company (the "Bank"). The Company is a multi-state bank holding company headquartered in Danville, Virginia. The Bank is a community bank organization serving Virginia and North Carolina with 26 banking offices. In addition to traditional retail, commercial and mortgage offerings, the Bank also provides trust and investment services through its Trust and Investment Services Division. 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.
