WrestleMania VII was the seventh annual WrestleMania professional wrestling pay-per-view event produced by the World Wrestling Federation (WWF). It took place on March 24, 1991, at the Los Angeles Memorial Sports Arena in Los Angeles, California. The main event saw Hulk Hogan defeat Sgt. Slaughter for the WWF World Heavyweight Championship as part of a controversial storyline in which Sgt. Slaughter portrayed an Iraqi sympathizer during the United States' involvement in the Gulf War. Significant events on the undercard included The Undertaker's WrestleMania debut and the beginning of his renowned winning streak, a retirement match between "Macho King" Randy Savage and The Ultimate Warrior leading to the former's reuniting with estranged love Miss Elizabeth, as well as the final match of the original Hart Foundation, after which Bret Hart became primarily a singles wrestler.

WrestleMania VII was originally scheduled to be held at the Los Angeles Memorial Coliseum, but the WWF decided to move the event to the adjacent Los Angeles Memorial Sports Arena. The WWF's stated reason for the venue change was that it had security concerns in the wake of Sgt. Slaughter's portrayal of an Iraqi sympathizer during the Gulf War. The actual reason was due to poor advanced ticket sales, and the company have difficulty filling the estimated 100,000 seats available. The official attendance of WrestleMania VII held at the Los Angeles Memorial Sports Arena was 16,158.
