Carnot Posey (August 5, 1818 – November 13, 1863) was a Mississippi planter and lawyer, and a Confederate general in the American Civil War. He was mortally wounded at the Battle of Bristoe Station. He was transported for care to the University of Virginia, where the rooms on the Lawn all served as Confederate hospital rooms. He was placed in the same room (Room 33 West Lawn) where he lived many years earlier as a UVa Law student and later died in that room of his wounds.
