UFC 184: Rousey vs. Zingano was a mixed martial arts event held on February 28, 2015 at Staples Center in Los Angeles, California.

A UFC Middleweight Championship bout between Chris Weidman and Vitor Belfort was expected to serve as the event headliner. The much delayed pairing was previously scheduled to take place at UFC 173 and also at UFC 181. However, on January 30, the UFC announced that Weidman had pulled out of the bout, citing an injury he sustained in training. Subsequently, a UFC Women's Bantamweight Championship bout between current champion Ronda Rousey and top contender Cat Zingano was promoted to the main event. Belfort was offered an interim title fight first against Lyoto Machida and then Gegard Mousasi as a replacement for Weidman, but he declined and stated that he would only fight for the full title.

Neil Magny was briefly linked to a bout with Josh Koscheck at the event. However, Magny was pulled from the fight in favor of a bout with Kiichi Kunimoto at UFC Fight Night 60. Koscheck faced Jake Ellenberger instead.

A bout between touted newcomer Holly Holm and Raquel Pennington, originally booked for UFC 181 and ultimately scrapped due to Holm being injured, served as the co-headliner.

Mark Muñoz was very briefly scheduled to a bout with Caio Magalhães at the event. However, shortly after the bout was announced by the UFC, Magalhães indicated that he would not be able to compete at the event due to a lingering infection after recent dental surgery, which would require additional surgery. Muñoz stayed on the card and faced returning UFC veteran Roan Carneiro.
