UFC 98: Evans vs. Machida was a mixed martial arts event held by the Ultimate Fighting Championship (UFC) on May 23, 2009 in Las Vegas, Nevada.

A title unification match between the UFC Interim Heavyweight Champion Frank Mir and UFC Heavyweight Champion Brock Lesnar was originally slated to be the main event, but was postponed until UFC 100 due to a knee injury to Mir.
