James Nathaniel Toney (born August 24, 1968) is an American former professional boxer who competed from 1988 to 2017. Known for his slick, defensively oriented style of boxing, Toney is a former three-weight world champion, having held the IBF and lineal middleweight titles from 1991 to 1993; the IBF super middleweight title from 1993 to 1994; and the IBF cruiserweight title in 2003. Additionally he challenged twice for a world heavyweight title, and was victorious the first time but was later stripped due to a failed drug test.
In 1991 and 2003, Toney was voted Fighter of the Year by The Ring magazine and the Boxing Writers Association of America. In 2011, The Ring magazine ranked him as tenth on their list of the "10 best middleweight title holders of the last 50 years." He has also made a one-time appearance in mixed martial arts, losing to Randy Couture at UFC 118 in 2010. Outside of sports, Toney played the role of Joe Frazier in the 2001 film Ali.
