HMCS Integrity was a cutter built by the Colonial Government of New South Wales in 1804. She was the first vessel ever launched from a New South Wales dockyard and carried goods between the colony's coastal settlements of Norfolk Island, Newcastle, New South Wales, Van Diemen's Land and Port Jackson. In 1804 she took part in a series of voyages to Van Diemen's Land with the aim of founding a colony at Port Dalrymple, the site of the modern settlement of George Town, Tasmania.
