HMCS Annapolis was an Annapolis-class destroyer that served in the Royal Canadian Navy and later, the Canadian Forces. She was the second Canadian naval unit to carry this name. Named for the Annapolis River that flows through Nova Scotia, the ship entered service in 1964, the last of the St. Laurent-class design. Serving through the Cold War, Annapolis was decommissioned in 1998 before going through a protracted legal battle for use as an artificial reef. She was finally scuttled as such in April 2015 in Howe Sound, British Columbia.
