HMCS Shawinigan was a Flower-class corvette that served with the Royal Canadian Navy during the Second World War. She served primarily in the Battle of the Atlantic protecting convoys. She was sunk in 1944. She was named for Shawinigan, Quebec.

Flower-class corvettes like Shawinigan serving with the Royal Canadian Navy during the Second World War were different from earlier and more traditional sail-driven corvettes. The "corvette" designation was created by the French as a class of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877. During the hurried preparations for war in the late 1930s, Winston Churchill reactivated the corvette class, needing a name for smaller ships used in an escort capacity, in this case based on a whaling ship design. The generic name "flower" was used to designate the class of these ships, which – in the Royal Navy – were named after flowering plants.

Corvettes commissioned by the Royal Canadian Navy during the Second World War were named after communities for the most part, to better represent the people who took part in building them. This idea was put forth by Admiral Percy W. Nelles. Sponsors were commonly associated with the community for which the ship was named. Royal Navy corvettes were designed as open sea escorts, while Canadian corvettes were developed for coastal auxiliary roles which was exemplified by their minesweeping gear. Eventually the Canadian corvettes would be modified to allow them to perform better on the open seas.

Shawinigan was ordered 24 January 1940 as part of the 1939–1940 Flower-class building program and laid down on 4 June 1940 by Davie Shipbuilding & Repairing Co. Ltd. at Lauzon, Quebec. However she was not launched until almost a year later on 16 May 1941.Shawinigan was commissioned on 19 September 1941 at Quebec City, Quebec.

Upon entering active service, Shawinigan joined Sydney Force in November 1941. She served there until transferring to the Newfoundland Escort Force on 13 January 1942. She made three round trips across the Atlantic before being assigned to Halifax Force in June 1942. She spent only a few months before being assigned to WLEF. Almost simultaneous with her new assignment, she went for a major refit that was completed in March 1943. In June she joined EG W-3. In April 1944 she underwent another refit and transferred to EG W-2 and worked up in Bermuda.
