The Slave Trade Act of 1794 bans the export of slaves from the United States, and prohibits American citizens from outfitting a ship for the purpose of importing slaves.

The Slave Trade Act of 1794 was a law passed by the United States Congress that prohibited the building or outfitting of ships in U.S. ports for the international slave trade. It was signed into law by President George Washington on March 22, 1794. This was the first of several anti-slave-trade acts of Congress. In 1800, Congress strengthened it by sharply raising the fines and awarding informants the entire value of any ship seized, as well as additional prohibitions on American investment and employment in the trade.

Slave ships were large cargo ships specially built or converted from the 17th to the 19th century for transporting slaves. Such ships were also known as "Guineamen" because the trade involved human trafficking to and from the Guinea coast in West Africa.

March 22 is the 81st day of the year in the Gregorian calendar; 284 days remain until the end of the year.
