USS Regulus (AK-14) was an Regulus-class cargo ship acquired by the U.S. Navy for service in World War II.

Commissioned in full at New York City 14 December 1940, Regulus steamed via the U.S. West Coast to Pearl Harbor, her homeport from February 1941 through the end of World War II.

At Midway on 7 December 1941, Regulus returned to Pearl Harbor on the 14th, then sailed to the West Coast, whence, through May, she carried cargo to Hawaii.

Assigned then to ServRon 8, she operated among the Samoan and Ellice Islands until she resumed west coast-Hawaii cargo runs in April 1944.

Decommissioned 25 March, she was struck from the Navy list 17 April; transferred to the Maritime Commission 1 July; and sold for scrap to the Kaiser Co., on 29 September 1947.
