Dorset Land District is one of the twenty land districts of Tasmania which are part of the Cadastral divisions of Tasmania. It was formerly one of the 18 counties of Tasmania. It is located at the north-eastern tip of Tasmania. It is bordered by the Tamar River to the west, the George River to the south-east, and the North Esk River to the south. It includes Bridport, George Town and Scottsdale. It also includes some northern suburbs of Launceston. The local government area of the Dorset Council is in a similar region. It is named after the county of Dorset in England, and towns in the area were named after towns in that county. https://web.archive.org/web/20071019140730/http://www.bridportradio.co.uk/content/view/367/99/
