Thomas Arthur Green (June 9, 1948 – February 28, 2021) was a Mormon fundamentalist in Utah who was a practitioner of plural marriage. After a high-profile trial, Green was convicted by the state of Utah on May 18, 2001, of four counts of bigamy and one count of failure to pay child support. This decision was upheld by the Utah State Supreme Court in 2004. He was also convicted of child rape, on the basis that one of his wives had his child at the age of 14. The wife in question was his stepdaughter before they were married; she was the daughter of his first polygamous wife. In total, he served six years in prison and was released in 2007.
