The Bidjara people, also spelt Bitjara or Bithara, are an Aboriginal Australian people of south-western Queensland. They spoke a dialect of the Ngura language. They are not to be confused with the Warrego River Pitjara or the Badjiri of the Paroo River, both of whose traditional lands are further to the east of the state.
Norman Tindale estimated their lands as encompassing approximately , centered around Bulloo Downs, south to the south to Bulloo Lake floodplain. Their western border lay at the Grey Range. Their northern limits were at Orient, and their eastern frontier was around Clyde.
The Bitjara included circumcision in their initiatory rites.
