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.

The main event of Bound for Glory IV was a standard wrestling match for the TNA World Heavyweight Championship, pitting the champion Samoa Joe against the challenger Sting. Sting won the match to become the new champion. Another highly promoted contest on the card was between Kurt Angle and Jeff Jarrett, with Mick Foley serving as the Special Ringside Enforcer. Jarrett was the victor of the encounter. TNA held a Three Way War between A.J. Styles, Booker T, and Christian Cage at the event, which Booker T won. The TNA World Tag Team Championship was defended in a Four Way Tag Team Monster's Ball match with Steve McMichael as the Special Guest Referee, in which the champions Beer Money, Inc. (James Storm and Robert Roode) fought the team of Abyss and Matt Morgan, The Latin American Xchange (Hernandez and Homicide), and Team 3D (Brother Devon and Brother Ray). Beer Money, Inc. pinned Hernandez to retain the championship in the contest.
