MV Cape Don is a former lighthouse tender, now a museum ship in Waverton, New South Wales, Australia. Built and launched by the State Dockyard at Newcastle, New South Wales in 1962 for the Commonwealth Lighthouse Service, she serviced the lighthouses, lightships and buoys of the Australian coast from 1963 to the early 1990s. She is being restored by the labour of enthusiasts to become a museum and training ship. She is listed on the Australian Register of Historic Vessels. She is currently berthed at the former coal loading wharf in Balls Head Bay, Waverton, New South Wales.
