UFC 115: Liddell vs. Franklin was a mixed martial arts event held by the Ultimate Fighting Championship on June 12, 2010 at General Motors Place (now Rogers Arena) in Vancouver, British Columbia, Canada.

This was the fourth UFC event to be held in Canada, following UFC 83, UFC 97 and UFC 113 and the first UFC event held in British Columbia since they passed a bill to sanction MMA, on December 17, 2009. For a few days, this event location was in jeopardy because there were still no regulations in place to promote the sport professionally within Vancouver and Cincinnati was rumoured to be a possible location for moving this event. However, the problems were resolved and Dana White confirmed that the show will be going ahead in Vancouver on the scheduled date.

The main event was tentatively set to be a third bout featuring Ultimate Fighter coaches and former UFC Light Heayvweight Champions Chuck Liddell and Tito Ortiz. In March, rumours began to circulate that Rich Franklin would replace Ortiz as Liddell's opponent, after Ortiz had supposedly withdrawn from the fight. However, Dana White denied this via his Twitter account on March 13, 2010, noting that Liddell vs. Ortiz was still set to be the main event. Then, after the announcement, Ortiz had to withdraw from the match due to neck surgery.
