Melville Island is a small peninsula in Nova Scotia, Canada, located in the Northwest Arm of Halifax Harbour, west of Deadman's Island. It is part of the Halifax Regional Municipality. The land is rocky, with thin, acidic soil, but supports a limited woodland habitat. The peninsula now houses the clubhouse and marina of the Armdale Yacht Club. Melville Island has been the subject of a number of cultural works, most of which concern its use as a prison.
