UFC 65: Bad Intentions was a mixed martial arts competition held by the Ultimate Fighting Championship on November 18, 2006, at the ARCO Arena in Sacramento, California – the UFC's first show at this venue.

It was broadcast live on pay-per-view in the United States and Canada, and was later released on DVD.

UFC 169 on February 1, 2014, would later feature two non-interim title fights, with the lighter weight class as main event.

It was first officially announced to happen at UFC 63 during the July 17, 2006 edition of The Hot List on ESPNEWS.

The fight was announced before, without a date, at a press conference in Toronto, Ontario, Canada on April 7, 2006, and the matchup was alluded to—but not officially announced—during the pay-per-view broadcast of UFC 58.
