HMCS Givenchy was one of twelve Battle-class naval trawlers constructed for and used by the Royal Canadian Navy (RCN) during the First World War on the east coast.

The RCN's Battle-class trawlers formed part of the Canadian naval response to Admiralty warnings to Canada about the growing German U-boat threat to merchant shipping in the western Atlantic.

[4][a] This was considered to be the smallest gun that stood a chance of putting a surfaced U-boat out of action, and they also carried a small number of depth charges.

[7] Givenchy sailed to the east coast where for the 1918 shipping season, all the Battle-class trawlers were assigned to patrol and escort duties based out of Sydney, Nova Scotia.

[12] After the outbreak of the Second World War, Givenchy returned to RCN service on 15 April 1939 and was used as an accommodation ship for the Fisherman's Reserve on the west coast.
