Flinders Island is an island in the Bass Strait, located 20 km from Cape Portland being the north-eastern tip of Tasmania, Australia. It is the largest island in the Furneaux Group.
The island forms part of the state of Tasmania, and part of the Municipality of Flinders Island local government area. Note that Flinders Island is only one of the many islands included in the Municipal area, although Flinders Island itself is the only island with more than one permanent settlement and is by far the largest in the Furneaux Group.
