Iran Barkley (norn May 6, 1960) is an American former professional boxer who competed from 1982 to 1999. He held world championships in three weight classes, including the WBC middleweight title from 1988 to 1989, the IBF super middleweight title from 1992 to 1993, and the WBA light heavyweight title in 1992. 

As an amateur boxer, Barkley won a bronze medal in the middleweight division at the 1982 World Championships.Known as "The Blade", Barkley turned professional in December 1982, and first challenged for a world title against the highly skilled Italian Sumbu Kalambay, losing on points over fifteen rounds for the vacant WBA middleweight title in Livorno, Toscana, Italy in October 1987.

Barkley returned in 1988 with a split decision over Sanderline Williams and a fifth-round stoppage of Michael Olajide, before winning the WBC middleweight title with a third-round knockout of Thomas Hearns, voted 1988 Upset of the Year by The Ring magazine.

In his next fight, Barkley lost his title via split decision in a 12-round war with Roberto Durán, in a fight proclaimed 1989 Fight of the Year by Ring magazine. Following the defeat to Duran, Barkley took on undefeated Michael Nunn for the IBF and lineal middleweight titles, dropping a close majority decision. 

He next fought Nigel Benn in a challenge for the WBO middleweight title and was stopped on the three-knockdown rule at the end of a wild first round in which both fighters were hurt.

After losing to Benn, Barkley underwent surgery for a detached retina and was inactive for a year. Barkley returned with two low-key wins at light heavyweight in 1991, then defeated Darrin Van Horn to win the IBF super middleweight title in two rounds in January 1992 in Paramount Theatre, New York. 

Just two months later, he went on to again defeat Hearns and take his WBA light heavyweight title via a twelve-round split decision. Barkley vacated the title without defending it, choosing instead to defend his super middleweight title against IBF and lineal middleweight champion James Toney. 

Barkley reportedly had trouble getting back down to the 168 lb weight limit and lost his IBF title via a corner retirement after nine rounds due to severe swelling around both eyes.

Barkley's final shot at a title would come against undefeated Henry Maske at light heavyweight for Maske's IBF title in Nordrhein-Westfalen, Germany in October 1994. Barkley again lost by corner retirement after nine rounds.

Barkley continued to fight after this loss, eventually moving up to the heavyweight division. His last fight of note was a June 1997 win for the WBB heavyweight title, a bout in which Barkley retired former WBA heavyweight champion Gerrie Coetzee with a 10th-round TKO.
