USS Chaffinch (AM-81) was a minesweeper acquired by the U.S. Navy during World War II for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing.

Chaffinch was built in 1928 by the Bethlehem Shipbuilding Corp., Quincy, Massachusetts, as Trimont; purchased by the Navy 29 November 1940, and commissioned 16 July 1941.

For the next year and a half, alert to the mounting German submarine menace, she swept for mines and patrolled waters off New York and New London, Connecticut.

Continuing her essential support to the movement both of coastwise convoys, and those bound for distant ports, Chaffinch again served at New York Harbor until 1 August 1945, when she cleared for Charleston, South Carolina.
