Billy Bailey (1947 - January 25, 1996) was a convicted murderer hanged in Delaware in 1996. He became the third person to be hanged in America since the resumption of executions in 1977 (the other two were Charles Rodman Campbell and Westley Allan Dodd, both in Washington). He is the last person in the United States to be executed in this manner thus far.

Bailey was found guilty of the murders in 1980. After his conviction the jury held that the crimes "were outrageously or wantonly vile, horrible, or inhuman" and recommended the death penalty.

Bailey was executed by the state of Delaware in 1996. He refused to exercise his option to choose lethal injection as a method of execution and was instead hanged. He became the third person to be hanged in the United States since the 1976 Supreme Court.
