ArenaBowl XXIV was the 24th edition of the championship in the Arena Football League (AFL). The American Conference champion, Jacksonville Sharks, defeated the National Conference champion, Arizona Rattlers, 73–70. It was played on August 12, 2011. The game was hosted at the site of the highest remaining seed throughout the playoffs, which was US Airways Center in Phoenix, Arizona, home of the Rattlers.

The ArenaBowl was scheduled to be played at the site of the highest seed who reaches the championship. Arizona finished with the best record during the regular season. In an interview with AFL Insider on May 9, AFL Commissioner Jerry Kurz said playing ArenaBowl XXV in 2012 at a neutral site is a strong option. The ArenaBowl was played at the highest seed in the game since the AFL's inception in 1987 until 2004. From 2005 to 2008, it was at a neutral site, Las Vegas and New Orleans. In 2010, the ArenaBowl returned to the highest remaining seed setting, as ArenaBowl XXIII was played at the Spokane Arena, home of the Spokane Shock, who won the game.

ArenaBowl XXIV was televised on NFL Network. The game was the highest watched Arena Football League game on the NFL Network, earning a 0.37 rating. That was up 200 percent from ArenaBowl XXIII on NFL Network. The previous record was set a week before when the 2011 AFL American Conference Championship game earned a 0.32 rating between the Georgia Force and Jacksonville Sharks, with the Sharks winning 64-55.
