UFC 289

UFC 289: Nunes vs. Aldana was a mixed martial arts event produced by the Ultimate Fighting Championship that took place on June 10, 2023, at the Rogers Arena in Vancouver, British Columbia, Canada.

Background
The event marked the promotion's 32nd overall visit to Canada and sixth to Vancouver, returning to the country for the first time since UFC Fight Night: Cowboy vs. Gaethje in September 2019.

A UFC Women's Bantamweight Championship trilogy bout between current two-time champion (also current UFC Women's Featherweight Champion) Amanda Nunes and former champion (also The Ultimate Fighter: Team Rousey vs. Team Tate bantamweight winner) Julianna Peña was expected to headline the event. However on May 2, Peña pulled out due to broken ribs and was replaced by Irene Aldana, who was scheduled to headline UFC Fight Night: Dern vs. Hill in a rematch against former title challenger Raquel Pennington. The latter served as a backup for the title bout.
