The fourth HMS Dominica (K507) was a Colony-class frigate of the United Kingdom which served in the Royal Navy during World War II.

The ship, originally designated a "patrol gunboat," PG-187, was ordered by the United States Maritime Commission under a United States Navy contract as USS Harman.

She was reclassified as a "patrol frigate," PF-79, on 15 April 1943 and laid down by the Walsh-Kaiser Company at Providence, Rhode Island, on 27 July 1943.

Transferred to the United Kingdom under Lend-Lease on 25 January 1944, the ship served in the Royal Navy as HMS Dominica (K507) on patrol and escort duty until 1945.

She was sold to the Sun Shipbuilding and Drydock Company of Chester, Pennsylvania, on 27 March 1947 for scrapping.
