Free State of Jones is a 2016 American historical war film inspired by the life of Newton Knight and his armed revolt against the Confederacy in Jones County, Mississippi, throughout the American Civil War. Written and directed by Gary Ross, the film stars Matthew McConaughey, Gugu Mbatha-Raw, Mahershala Ali, and Keri Russell.

Newton Knight was an American farmer, soldier and Southern Unionist in Mississippi, best known as the leader of the Knight Company, a band of Confederate Army deserters who resisted the Confederacy during the Civil War. Local legends tell of Knight and his men forming the "Free State of Jones" in the area in and around Jones County, Mississippi, at the height of the war. The nature and extent of the Knight Company's opposition to the Confederate government is disputed among historians. After the war, Knight joined the Republican Party and served in Mississippi's Reconstruction government as a deputy U.S. Marshal.
