Bell Bay is an industrial centre and port located on the eastern shore of the Tamar River, in northern Tasmania, Australia. It lies just south of George Town. In the year ended June 2021, 3.6 million tonnes of exports and imports passed through Bell Bay.

Bell Bay was connected to the Tasmanian Government Railways network in May 1974, when the 35 kilometre Bell Bay railway line opened, branching off the North East line at Nelson Creek to the north of Launceston. Primarily built to carry logs for export, today it carries intermodal containers to and from the port.
