HMCS Armentières was one of twelve Battle class naval trawlers used by the Royal Canadian Navy (RCN). Named after the Battle of Armentières, she was built by Canadian Vickers, at Montreal, and was commissioned on 5 June 1918. Along with HMCS Givenchy, and HMCS Thiepval, Armentières accompanied HMCS Stadacona on a trip to the west coast via the Panama Canal in early 1919.
