Reginald R. Gross (born January 1962) is an American convicted murderer and former professional boxer who competed from 1982 to 1988. His most notable wins were a first round knockout of future long-time IBF world Light-Heavyweight champion "Prince" Charles Williams, as well as upsets of undefeated Smokin' Bert Cooper (TKO8) and outstanding amateur and 16-0 pro Jimmy Clark (TKO9).^[1]

He was most famously stopped in one round by Mike Tyson, in an exciting but brief bout where he took the fight to the feared contender. He also suffered losses to Frank Bruno and Jesse Ferguson.

His final fight was in June 1988, on the Tyson/Spinks undercard, where he lost to Donovan Ruddock in the second round.

In 1989, he was arrested and convicted for three contract killings.^[2] He is currently serving his three life sentences with two of them consecutive with the initial part of his sentence served at the maximum security prison in Edgefield, South Carolina.^[2]

When interviewed in 2008 Gross was incarcerated at the US Penitentiary, Hazelton and had a 2014 parole hearing planned.^[3]

In September 2019, Gross petitioned the US Court of Appeals as he believed that he was eligible for mandatory release after thirty years, as his crimes occurred before the Sentencing Reform Act of 1984 came into effect. The Court found in favor of the Bureau of Prisons, who argued that because he is serving two consecutive life sentences, he would in fact need to serve thirty years on each of his two life sentences before being eligible for mandatory parole.^[4]

As of 2023 Gross was incarcerated at MCFP Springfield in Missouri with a release date of November 1, 2048.^[5]
