Joseph Lewis Clark (January 15, 1949 – May 2, 2006) was an American murderer executed by the State of Ohio. He was the 21st person executed by Ohio since the state resumed executions in 1999. Clark was sentenced to die on November 28, 1984, for the murder of 22-year-old David Manning during a gas station hold-up in Toledo, though he also confessed to the separate murder of a convenience store employee.
