James Demouchette (May 20, 1955 – September 22, 1992) was an American inmate in Texas, who was sentenced to death for the 1976 double-murder of two Pizza Hut clerks during a robbery in Houston. While imprisoned, he gained infamy as the "Meanest Man on Death Row" for his deviant behavior while housed on death row; he fatally stabbed another inmate with a homemade knife, and on another occasion he attacked three corrections officers with a knife. There were also reports of him setting fires around the prison. By the time of his execution in 1992, his case had attracted particular media attention due to his behavior. His case has also been used as an example by advocates of capital punishment.
