美国铸币局（英语：United States Mint）主要铸造美国流通硬币以作贸易和商业之用。其主要铸造设施位于费城，分局位于丹佛、三藩市和纽约西点。

铸币局根据美国国会通过的1792年铸币法案成立，设于美国国务院之下。根据法案条文，第一幢铸币大楼位于费城，即当时的美国首都。铸币局的首任总监是著名科学家戴维·里顿豪斯，现时则为Edmund C. Moy。1799年，铸币局成为独立组织，而根据1873年铸币法案，铸币局成为美国财政部辖下机构。1981年起，铸币局向美国财政部财务长负责。

The United States Mint primarily produces circulating coinage for the United States to conduct its trade and commerce. The Mint was created by Congress with the Coinage Act of 1792, and originally placed within the Department of State. Per the terms of the Coinage Act, the first Mint building was in Philadelphia, then the capital of the United States; it was the first building of the Republic raised under the Constitution. Today, the Mint's headquarters are in Washington D.C. which is not a coin producing facility. It operates mint facilities in Philadelphia, Denver, San Francisco, and West Point, New York and a bullion depository at Fort Knox, Kentucky. Official Mints (Branches) were once also located in Carson City, Nevada, C******te, North Carolina, Dahlonega, Georgia, New Orleans, Louisiana, Washington, D.C.; and even in Manila, in the Philippines.
