HMCS Assiniboine was a St. Laurent-class destroyer that served in the Royal Canadian Navy and later the Canadian Forces from 1956 to 1988. She was the second ship to bear the name. Entering service in 1956, the ship underwent conversion to a destroyer helicopter escort (DDH) in 1962, the conversion performed primarily by Victoria Machinery Depot. She was officially reclassed with pennant DDH 234 on 28 June 1963. After being paid off in 1988, the vessel was used as a harbour training ship until being discarded in 1995. The vessel sank under tow to the breakers that year.
