Nigel Benn vs. Iran Barkley was a professional boxing match contested on August 18, 1990, for the WBO middleweight title.

[3] After losing his WBC middleweight title to Roberto Durán in February 1989, Iran Barkley would get a shot at the IBF's version of the middleweight title when he challenged champion Michael Nunn six months later, though he would lose via unanimous decision.

[4] Despite the loss, Barkley secured another middleweight title fight, this time against the inaugural WBO champion Doug DeWitt.

Benn dominated the fight, knocking DeWitt down four times en route to a technical knockout victory.

[7] In July, after Barkley's left eye finally healed and he was cleared to return to boxing, the Benn–Barkley fight was made official.
