苏珊·安东尼银元（英语：Susan B. Anthony dollar）是1979至1981年间出产的一种1美元硬币，1981年时因公众反响不佳而停产，1999年又再度生产。这种硬币的诞生是为取代过于臃肿的艾森豪威尔银元，铸币局测试过多种形状和材质，但都遭到当时对铸币立法有强大影响的自动售货机制造业游说集团反对，最终决定采用的一种内边框有11个面的圆形坯饼。

硬币由美国铸币局首席雕刻师弗兰克·加斯帕罗设计，他起初设计的正面是自由女神头像，但多位国会议员和多个组织呼吁在硬币上描绘一位真实存在过的美国女性，最终入选为硬币主题的是民权活动家苏珊·安东尼。硬币反面则根据国会法案要求，保留艾森豪威尔银元的设计。

The Susan B. Anthony dollar was a United States dollar coin minted from 1979 to 1981, when the series was halted due to poor public reception, and again in 1999. Proposed as a smaller replacement for the cumbersome Eisenhower dollar, a number of shapes and compositions were tested, but all were opposed by the vending machine industry, a powerful lobby affecting coin legislation. Finally, a round planchet with an eleven-sided inner border was chosen for the smaller dollar.
