HMCS Trinity (MCB 157) was a Bay-class minesweeper built for the Royal Canadian Navy during the Cold War. Named after Trinity Bay in Newfoundland, she was built by Davie Shipbuilding in Lauzon, Quebec. Her keel was laid on 31 January 1952, she was launched on 31 July 1953, and she was commissioned on 16 June 1954. Trinity joined the First Canadian Minesweeping Squadron and sailed to the Caribbean for a training cruise in 1955. In May 1956, the squadron took part in NATO mine-sweeping exercises in the western Atlantic. Trinity was paid off on 21 August 1957 and transferred to Turkey on 31 March 1958 under the NATO Mutual Aid Agreement, where she was renamed Terme.

Bay-class ships were designed to replace older WWII-era minesweepers. They had wooden hulls with aluminum framing, displaced about 390 tons (400 t) standard and 412 tons (419 t) at deep load, and measured 152 feet (46 m) in length, with a beam of 28 feet (8.5 m) and a draught of 8 feet (2.4 m). They carried a crew of 38, could reach speeds of 16 knots, and had a range of 3,290 nautical miles at 12 knots. Armament included one 40 mm Bofors gun, along with minesweeping gear.

Renamed Terme, the ship entered Turkish service and served as Terme (hull number M 531) until 1991.
