Bound for Glory IV was a professional wrestling pay-per-view (PPV) event produced by the Total Nonstop Action Wrestling (TNA) promotion that took place on October 12, 2008 at the Sears Centre in Hoffman Estates, Illinois. It was the fourth event under the Bound for Glory name and the tenth event in the 2008 TNA PPV schedule.

The show was promoted as TNA's premier PPV event and their equivalent to the rival World Wrestling Entertainment's (WWE) WrestleMania. Eight professional wrestling matches and one untelevised match were featured on the event's card, four of which were for championships.

In the main event, Sting defeated Samoa Joe to become the new TNA World Heavyweight Champion. In other prominent matches, Jeff Jarrett defeated Kurt Angle, Booker T defeated AJ Styles and Christian Cage in a Three Way War, Beer Money, Inc. (James Storm and Bobby Roode) defeated The Latin American Xchange (Hernandez and Homicide), Abyss and Matt Morgan, and Team 3D (Brother Devon and Brother Ray) to retain the TNA World Tag Team Championship, and in the opening contest, Jay Lethal defeated Alex Shelley, Chris Sabin, Curry Man, Jimmy Rave, Johnny Devine, Petey Williams, Shark Boy, Sonjay Dutt and Super Eric in a Steel Asylum to determine the #1 contender to the Impact X Division Championship.

In October 2017, with the launch of the Global Wrestling Network, the event became available to stream on demand.
