Bruny Island is an island off the south-eastern coast of Tasmania, from which it is separated by the D’Entrecasteaux Channel. Storm Bay is located to the island's northeast. Both the island and the channel are named after French explorer Bruni d'Entrecasteaux. Its traditional Aboriginal name was Lunawanna Allonah, which survives as the name of two island settlements, Alonnah and Lunawanna.
