USS Harrison was a schooner chartered and outfitted by General George Washington during the American Revolution for the Continental Navy.

She was assigned to capture British supply ships as part of Washington's plans for the siege of Boston, Massachusetts, and to provide the Continental Army with whatever goods they carried.

Harrison, a former fishing schooner built in 1761, and named the Triton was chartered 22 October 1775 as part of the small fleet outfitted by General George Washington to capture much needed supplies and to aid him in the siege of Boston.

Under Captain William Colt the ship set sail from Plymouth, Massachusetts, where she had been obtained, on 26 October.

Captain Colt succeeded in capturing two British provision ships 5 November.
