HMCS Trillium was a Flower-class corvette that served in the Royal Canadian Navy. She was ordered for the Royal Navy from Canadian Vickers Ltd. in Montreal and laid down on 20 February 1940. She was launched on 26 June 1940, transferred to the RCN, and commissioned on 31 October 1940. She was named after the Trillium genus of flowering plants including wakerobin, tri flower, and birthroot.
Trillium escorted trade convoys between Halifax Harbour and Liverpool through the battle of the Atlantic. The ship was returned to the Royal Navy after it escorted the last HX convoy of the war. She was sold for civilian use as Olympic Winner in 1950 and renamed Otori Maru No. 10 in 1956.
