Roy Jones Jr. vs. Montell Griffin, billed as The Battle of the Undefeated, was a professional boxing match contested on March 21, 1997 for the WBC light heavyweight championship.

For Jones' first defense, he was matched up against the undefeated Montell "Ice" Griffin, who in his previous fight had defeated James Toney for the second time to capture the less-regarded WBU light heavyweight title.

Prior to the fight, Griffin was seen by some as possibly the greatest challenge Jones, who was ranked by The Ring magazine as the number-one pound-for-pound fighter in all of boxing, had faced in his professional career.

Jones, who had rarely lost rounds on the scorecards, was taken to the limit by Griffin, who controlled the early portion of the fight.

Griffin initially talked of a unification match with then-WBA and IBF light heavyweight champion Virgil Hill, but he instead agreed to a rematch with Jones less than five months after their first fight on 7 August.
