Thomas Posey (1750-1818) was a military and political figure in the decades following the American Revolution. He was a member of the Virginia committee of correspondence, and served as an officer during the Revolutionary War. Serving in the U.S. Army after the revolution, he rose to the rank of brigadier general in 1793. In 1794 he moved to Kentucky, where he would serve as a state Senator, and later as the lieutenant governor. He moved to Louisiana, and served as a U.S. Senator from that state in 1812-1813. After he was defeated for re-election, he was appointed territorial Governor of Indiana. When Indiana became a state in 1816, he ran unsuccessfully for Governor. In the last two years of his life, he served as an Indian agent in Illinois.

Posey was dogged by rumors that he was the illegitimate son of George Washington. Posey grew up on land adjacent to Mt. Vernon, the Posey and Washington families were close, and Posey benefited from Washington's patronage early in his career. However, the rumors are dismissed by General Posey's biographer, John Thornton Posey.

Posey County, Indiana named for Thomas Posey.
