Capital punishment is a legal penalty in the U.S. state of Utah.

Gary Mark Gilmore was an American criminal who gained international attention for demanding the implementation of his death sentence for two murders he had admitted to committing in Utah. After the U.S. Supreme Court upheld a new series of death penalty statutes in the 1976 decision Gregg v. Georgia, he became the first person in almost ten years to be executed in the United States. These new statutes avoided the problems under the 1972 decision in Furman v. Georgia, which had resulted in earlier death penalty statutes being deemed "cruel and unusual" punishment, and therefore unconstitutional. Gilmore was executed by a firing squad in 1977. His life and execution were the subject of the 1979 nonfiction novel The Executioner's Song by Norman Mailer, and 1982 TV film of the novel starring Tommy Lee Jones as Gilmore.
