Royal Rumble (2011) was the twenty-fourth annual Royal Rumble professional wrestling pay-per-view event produced by World Wrestling Entertainment (WWE). It took place on January 30, 2011 at the TD Garden in Boston, Massachusetts and featured talent from the Raw and SmackDown brands. As has been customary since 1993, the Royal Rumble match winner received a match at that year's WrestleMania (in this instance: WrestleMania XXVII) for his choice at either the WWE Championship or the World Heavyweight Championship.

Four professional wrestling matches were featured on the event's supercard, a scheduling of more than one main event. The main event was the annual Royal Rumble match featuring 40 participants from both brands, instead of the usual number of 30. Alberto Del Rio, the thirty-eighth entrant, won the match by last eliminating Santino Marella, the thirty-seventh entrant. The primary match on the Raw brand was for the WWE Championship, between reigning champion The Miz and Randy Orton, which The Miz won to retain the championship. The primary match on the SmackDown brand was Edge versus Dolph Ziggler for the World Heavyweight Championship, which Edge won, to retain the title. The other featured match on the card was a Fatal Four Way match for the WWE Divas Championship between Eve Torres, Natalya, Layla and Michelle McCool, which Torres won to win the championship.

Eduardo Gory "Eddie" Guerrero Llanes (October 9, 1967 – November 13, 2005) was a Mexican-American professional wrestler born into the Guerrero wrestling family. He wrestled in Mexico and Japan for several major professional wrestling promotions. In the United States, Guerrero wrestled in Extreme Championship Wrestling (ECW), World Championship Wrestling (WCW), and in World Wrestling Entertainment (WWE). Guerrero's gimmick was that of "Latino Heat", a crafty, resourceful wrestler who would do anything to win a match. His catchphrase became "I Lie! I Cheat! I Steal!," which was used in one of his entrance themes. Guerrero partly used this phrase in his autobiography Cheating Death, Stealing Life.

Despite being a villain for most of his career, he got over in and outside the ring being the youngest, yet most popular and successful of the Guerrero brothers. Guerrero was widely regarded as one of the most respected and gifted technical wrestlers in history. Throughout his career, Guerrero encountered various substance abuse problems outside of wrestling, including alcoholism and an addiction to painkillers. His real-life problems were sometimes integrated into his storylines. Notwithstanding these issues, Guerrero won 23 titles during his career, including the WWE Grand Slam Championship.
