| 1 | Hulk Hogan WWF World Heavyweight Champion — Main Event The centerpiece of WrestleMania III and the WWF's biggest star. Hogan had been WWF World Heavyweight Champion since winning the title from the Iron Sheik at Madison Square Garden on January 23, 1984 — a reign of over three years heading into WrestleMania III. His championship defence against André the Giant was the most commercially successful match in WWF history to that point and the defining moment of the 1980s wrestling boom. | WWF World Heavyweight Champion | vs. André the Giant | Won — retained title |
| 2 | André the Giant WWF World Heavyweight Championship Challenger — Main Event The Eighth Wonder of the World made his first WrestleMania singles match appearance at WrestleMania III. André had been a beloved babyface for decades before Bobby Heenan's management turned him heel for this programme. His size, mystique, and claimed undefeated streak made him the most credible challenger Hulk Hogan had ever faced. André's deteriorating health made this one of his final elite-level performances. | Challenger — WWF World Heavyweight Championship | — | Lost |
| 3 | Randy 'Macho Man' Savage WWF Intercontinental Champion — Match of the Year Randy Savage entered WrestleMania III as the WWF Intercontinental Champion and the most technically demanding performer on the roster. His 414-day IC title reign, his meticulous preparation of the WrestleMania match, and his extraordinary chemistry with Steamboat produced what is widely regarded as one of the greatest professional wrestling matches in history. | WWF Intercontinental Champion | vs. Ricky Steamboat | Lost — title change |
| 4 | Ricky 'The Dragon' Steamboat New WWF Intercontinental Champion — Match of the Year Ricky Steamboat's WrestleMania III performance is the most celebrated of his career and arguably the finest 15 minutes in WrestleMania history. His recovery from the ring bell throat injury, his six months of emotional build, and his in-ring mastery against Savage produced a championship victory and match that has defined what WrestleMania excellence can be for nearly four decades. | Challenger — WWF Intercontinental Championship | — | Won — New IC Champion |
| 5 | 'Rowdy' Roddy Piper Hair vs. Hair — Retirement Match Roddy Piper competed at WrestleMania III in what he announced as his final professional wrestling match before departing for a Hollywood acting career. His Hair vs. Hair victory over Adrian Adonis was an emotional farewell that the Silverdome crowd embraced completely. Piper would return to wrestling multiple times over subsequent years, but this WrestleMania III performance represented his most significant farewell statement. | Hair vs. Hair challenger — retirement match | vs. Adrian Adonis | Won by submission |
| 6 | Bret 'Hitman' Hart Hart Foundation — Six-Man Tag Match Bret Hart competed at WrestleMania III as one-half of the WWF Tag Team Champions The Hart Foundation, teaming with Jim Neidhart and crooked referee Danny Davis. Hart's performance showcased the technical brilliance that would eventually make him a multi-time WWF World Champion, though his role at WM3 was primarily that of a superior tag team performer. | WWF Tag Team Champion — Hart Foundation | — | Won |
| 7 | Jake 'The Snake' Roberts Singles Match vs. Honky Tonk Man Roberts competed at WrestleMania III despite suffering legitimate nerve damage from Honky Tonk Man's guitar shot. The match marked Roberts' official babyface turn — a character evolution that would define his most commercially successful WWF period in 1987-88, including the beginning of his legendary programme with the Million Dollar Man Ted DiBiase. | Babyface — singles match | — | Lost to Honky Tonk Man |
| 8 | King Kong Bundy Six-Man Mixed Match After serving as the main event opponent at WrestleMania 2, King Kong Bundy's WrestleMania III role was significantly diminished — competing in the novelty midget wrestler six-man match. His disqualification for bodyslamming Little Beaver became one of the event's most talked-about moments, though not for the most flattering reasons. | Six-man tag — mixed midget match | — | DQ loss — bodyslammed Little Beaver |
