HMCS Eyebright was a Flower-class corvette that served mainly with the Royal Canadian Navy during the Second World War in the Battle of the Atlantic.

[3][4][5] The "corvette" designation was created by the French for classes of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.

[8] She was ordered for the Royal Navy (RN) as HMS Eyebright as part of the 1939-1940 Flower-class building program.

She could be told apart from other Canadian Flowers by her lack of minesweeping gear and the siting of the after gun tub amidships.

In December 1941 she left for a two-month refit returning in January to serve briefly with escort groups N14 and N13.

[10] The ship was broken up by South African Metal & Machinery Pty Ltd in Cape Town in February 1965.
