Marvin Gayle Gray (August 7, 1954 – July 23, 2013) was an American serial killer. Being a powerlifter, Gray, while imprisoned, achieved incredible results in powerlifting, almost breaking world records.

In the 2000s, he was considered the most dangerous prisoner in the state of Colorado, being convicted of one murder and confirmed to have committed at least two others, personally confessing to killing 41 people across 8 different states from 1971 to 1992. However, the credibility of his testimony continued to be disputed until his death.
