HMCS Windflower was a Royal Canadian Navy Flower-class corvette which took part in convoy escort duties in the Battle of the Atlantic during the Second World War.

[2][3][4] 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.

[7] Windflower was ordered on 22 January 1940 as part of the 1939-1940 Flower-class building program and laid down at George T. Davie & Sons Ltd., Lauzon on 24 February 1940.

She made three round trips from St. John's to Iceland only interrupted by a short refit at Liverpool, Nova Scotia from August to mid-October.

[11] On 7 December 1941, Windflower was escorting Convoy SC.58 when she collided with Dutch merchant Zypenberg in dense fog on the Grand Banks at 46° 19N, 49° 30W.
