Henry Ruhl (died April 27, 1945) was the only person executed in Wyoming by the United States Federal Government. This was also the second-to-last pre-Furman execution in the state and third-to-last as of 2015[update].
Ruhl was convicted for a murder committed on a government reservation, which made it a federal capital crime. Ruhl was put to death by gas chamber in the Wyoming State Penitentiary (Rawlins). He was 36 at time of his death.
Ruhl's execution was the first under new President Harry S. Truman.
