HMCS Dauphin was a Flower-class corvette that served in the Royal Canadian Navy during the Second World War.

[3][4][5] 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.

[6] During the hurried preparations for war in the late 1930s, Winston Churchill reactivated the corvette class, needing a name for smaller ships used in an escort capacity, in this case based on a whaling ship design.

She was laid down 6 July 1940 by Canadian Vickers Ltd. at Montreal, Quebec and launched on 24 October later that year.

On the night of 9–10 March U-229 torpedoed the tramp steamers Nailsea Court, which sank, and Colmore, which was damaged and abandoned.

It took Dauphin four hours to repair her steering gear and return to the boat.

She was sold for conversion to a merchant ship and in 1949 entered service as Cortes under a Honduran flag.
