Boat Harbour is both a geographical location and a population region (Australian Postcode 7321) on the north-west coast of Tasmania. It was originally named Jacobs' Boat Harbour after Captain John Jacobs, master of small vessels owned by the Van Diemen's Land Company trading between its establishments at Circular Head and Woolnorth with Launceston between the late 1820s and the 1840s. It is part of a rich agricultural district (dairying, potatoes, vegetables).
