Lunawanna is a small township on the western side of Bruny Island, Tasmania, facing the D'Entrecasteaux Channel. It is named after part of the Tasmanian aboriginal name for Bruny Island, Lunawanna-alonnah, a nearby township about 5 kilometres (3.1 mi) to its north being named Alonnah.
Lunawanna is in the federal electorate of Franklin, the Tasmanian House of Assembly division of Franklin, and the Tasmanian Legislative Council division of Huon. The Bruny Island local council amalgamated with Kingborough council in 1994 and Lunawanna is located in the Kingborough Council local government area.
Lunawanna has a public toilet at the community hall, a jetty, and a post box. Bruny Island Premium Wines is located at Lunawanna. The closest food store, post office, and police station are located in Alonnah, 7 kilometres (4.3 mi) to the north. The only petrol available on Bruny Island is at the Adventure Bay store, 19 kilometres (12 mi) away via Bruny Island Main Road.
On the last Saturday evening of every month an amateur talent night (the Lunawanna Jamboree - until 2015 named Hoppy's Jamboree, in honour of its founder) is held in the Lunawanna Memorial hall.
