HMCS Qu'Appelle was a Mackenzie-class destroyer that served in the Royal Canadian Navy and later the Canadian Forces. The ship's insignia and logo was the head of a fox facing forward centered in a diagonal line double white with a red center sqiggley line from the top left to bottom right. The moniker of the ship was "Follow the Fox".

She is the second Canadian naval unit to carry the name HMCS Qu'Appelle. Qu'Appelle was named for the Qu'Appelle River which runs through Saskatchewan and Manitoba in Canada. Entering service in 1963, the ship was largely used as a training ship on the west coast. She was decommissioned in 1994 and sold for scrapping.

The Mackenzie class was an offshoot of the St. Laurent-class design. Initially planned to be an improved version of the design, budget difficulties led to the Canadian government ordering a repeat of the previous Restigouche class, with improved habitability and better pre-wetting, bridge and weatherdeck fittings to better deal with extreme cold. The original intention was to give the Mackenzie class variable depth sonar during construction, but would have led to delays of up to a year in construction time, which the navy could not accept.

The Mackenzie-class vessels measured 366 feet (112 m) in length, with a beam of 42 feet (13 m) and a draught of 13 feet 6 inches (4.11 m). The Mackenzies displaced 2,880 tonnes (2,830 long tons) fully loaded and had a complement of 290.

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