USS Loyalty (AMc-88) was an Accentor-class coastal minesweeper acquired by the U.S. Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing.

Loyalty was laid down by Fulton Shipyard, Antioch, California, 8 May 1941; launched 23 August 1941; sponsored by Mrs. Donald Noackk; and placed in service 17 January 1942.

Assigned to the 14th Naval District, Loyalty, performed patrol and minesweeping operations out of Pearl Harbor.

Following conversion to an underwater location ship, Loyalty sailed 1 May 1945 for the western Pacific.

While en route to Unten Ko, Okinawa, 16 September, she struck a reef and grounded.
