 
The following is a list of people executed by the U.S. state of Oklahoma before 1972, when capital punishment was briefly abolished by the Supreme Court's ruling in "Furman v. Georgia". For people executed by Oklahoma after the restoration of capital punishment by the Supreme Court's ruling in "Gregg v. Georgia" (1976), see List of people executed in Oklahoma.
Background.
In 1915, Oklahoma adopted electrocution as its main form of capital punishment, with a designated execution chamber being added to the state penitentiary in McAlester. From that year to 1972, 83 prisoners (all male) were executed in the state penitentiary. 82 were electrocuted; one of the prisoners, sentenced to death by the federal government under the "Lindbergh law", was hanged instead at his request. (Hanging was retained as an alternative method.)
