UFC 102: Couture vs. Nogueira is an upcoming mixed martial arts event to be held by the Ultimate Fighting Championship (UFC) on August 29, 2009 at the Rose Garden in Portland, Oregon. It will feature former UFC Heavyweight and Light Heavyweight champion, Randy Couture, facing off against former PRIDE Heavyweight champion and former UFC Interim Heavyweight champion, Antonio Rodrigo Nogueira.

Randy Couture was originally offered a title defense against Antônio Rodrigo Nogueira at UFC 81, however turned the fight down after his resignation from the UFC in October 2007. While Couture and the UFC sorted out their legal issues, Nogueira defeated Tim Sylvia for the UFC Interim Heavyweight Championship becoming the first fighter to hold both PRIDE and UFC title belts. Nogueira was then set to coach against Frank Mir on the eighth season of The Ultimate Fighter with the two facing off for the Interim Championship after the season aired. In the meantime Couture and the UFC reconciled and it was announced that he would return to the Octagon to defend his title against Brock Lesnar at UFC 91.Neither Couture or Nogueira were successful in their defense efforts and will now face each other in what amounts to the loser bracket of the UFC's mini heavyweight tournament.
