HMCS Cape Breton was a Royal Canadian Navy Cape-class maintenance ship. Originally built for the Royal Navy as HMS Flamborough Head in 1944, she was transferred in 1952. Upon her commissioning she was the second ship to bear the name Cape Breton. She served operationally from 1953–1964, when she was laid up. She was used as a floating machine shop until the late-1990s, before being sold for use as an artificial reef off the coast of British Columbia.
