The 2007 Royal Rumble was the 20th annual Royal Rumble professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE). It was held for wrestlers from the promotion's Raw, SmackDown!, and ECW brand divisions. The event took place on January 28, 2007, at the AT&T Center in San Antonio, Texas, and was the second Royal Rumble held in San Antonio after the 1997 event. This marked the ECW brand's first participation in the Royal Rumble, which became WWE's third brand in mid-2006. As has been customary since 1993, the Royal Rumble match winner received a world championship match at that year's WrestleMania. For the 2007 event, the winner received their choice to challenge for either Raw's WWE Championship, SmackDown!'s World Heavyweight Championship, or the ECW World Championship at WrestleMania 23, marking the first time that three titles were an option.

Five professional wrestling matches were featured on the event's supercard, a scheduling of more than one main event. The main event was the 2007 Royal Rumble match, which featured wrestlers from all three brands. SmackDown!'s The Undertaker, the 30th entrant, won the match by last eliminating Raw's Shawn Michaels, the 23rd entrant. The primary match on the Raw brand was a Last Man Standing match for the WWE Championship between John Cena and Umaga. Cena won the match and retained the title after Umaga was unable to get to his feet before the referee counted to ten. The predominant match on the SmackDown! brand was Batista versus Mr. Kennedy for the World Heavyweight Championship, which Batista won by pinfall after executing a Batista Bomb. The featured match on the ECW brand was between Bobby Lashley and Test for the ECW World Championship, which Lashley won after Test was counted out.
