USS YP-389 was a United States Navy yard patrol (YP) boat that served in World War II. The ship was built in 1941 as the fishing trawler Cohasset at the Fore River Shipyard in Quincy, Massachusetts for R. O'Brien and Company.

Acquired by the Navy on 6 February 1942, she was originally designated as a coastal minesweeper, AMc-202, but was reclassified as a District Patrol Craft, YP-389, on 1 May 1942. The 170 long tons (170 t) ship was equipped with one 3 in (76 mm) dual purpose gun to protect the ship from enemy aircraft and surfaced submarines and two .30 in (7.6 mm) machine guns.

Six sailors died when YP-389 was attacked by a U-701 on 19 June. There were 18 survivors. On the day of the attack, YP-389's 3 in (76 mm) gun was inoperative, and she could only return fire with her machine guns.

On 9 September 2009, a research mission led by NOAA announced that the boat had been found and photographed 20 mi (32 km) off Cape Hatteras, North Carolina by the Nancy Foster. The wreck rests in about 300 ft (91 m) of water in a region known as the "Graveyard of the Atlantic", where several U.S. and British naval vessels, merchant ships, and German U-boats sunk during the Battle of the Atlantic.
