HMCS Nipigon was an Annapolis-class destroyer that served in the Royal Canadian Navy and later the Canadian Forces. She was the second Canadian naval unit to carry this name. Entering service in 1964, she was named for the Nipigon River that flows through Ontario.

Nipigon served throughout the Cold War on the Atlantic coast of Canada. She was paid off in 1998 and sold for use as an artificial reef off the coast of Quebec.

The Royal Canadian Navy had intended to place a six ship order under the Mackenzie class of destroyer escorts; however, during the design phase, the last two vessels ordered were altered to the St. Laurent-class DDH design and were classed under the new Annapolis designation.

The ships measured 366 feet (112 m) in length, with a beam of 42 feet (13 m) and a draught of 13 feet 2 inches (4.01 m). Initially, the ships displaced 2,400 tonnes (2,400 long tons) and had a complement of 228.

The ships were powered by two Babcock & Wilcox boilers connected to the two-shaft English-Electric geared steam turbines providing 30,000 shaft horsepower (22,000 kW). This gave the ships a maximum speed of 28 knots (52 km/h; 32 mph).

The ships were initially armed with two 3-inch (76 mm)/50 caliber dual-purpose guns mounted in a single turret forward. The extra topweight of the helicopter required the return of the American Mk 33 3-inch gun over the heavier 3-inch/70 caliber guns used on the preceding class. The guns could fire 45 – 50 rounds per minute with a lifespan of 2,050 rounds. The guns were placed in a Mk 33 mount. The mounting allowed the guns to elevate from −15° to 85°. The elevation rate was 30° per second and train rate was 24° per second. The mounts could train 360°.
