This is a list of various things that took place in 1983.
- The Road Warriors make their debut as a team in Georgia Championship Wrestling
- Pro Wrestling Illustrated revokes recognition of the World Wrestling Federation as a world title promotion in its magazine, citing the WWF's regionalization (limiting events to its home base in the Northeastern US) and its unwillingness to give shots at WWF Champion Bob Backlund to face challengers
- Vince McMahon withdraws the WWF's membership in the National Wrestling Alliance and embarks on his plans to expand his promotion outside the Northeast and take over the wrestling industry, beginning with syndicating his TV shows WWF Championship Wrestling and WWF All-Star Wrestling to other American TV markets
- The WWF purchases the rights to the World Women's singles and tag team titles, which were previously NWA-sanctioned titles, from The Fabulous Moolah and renames them as WWF championships
- The WWF publishes its first magazine, Victory Magazine, the predecessor to WWF Magazine. "Superfly" Jimmy Snuka, at the time the WWF's most popular superstar and who was in the midst of a brutal feud with The Magnificent Muraco, was the first cover-featured superstar.
- 5 - During a television taping at the Hamburg (Pennsylvania) Fieldhouse, following a squash match where the Magnificent Muraco defeated Victor Mercado, Muraco famously eats a meatball sandwich and drinks a glass of soda in between wrestling. Following the match, Muraco's manager, Captain Lou Albano slips on the floor on part of the sandwich, drawing laughter from the crowd and commentators Vince McMahon, Jr. and Pat Patterson (and Muraco doing all he can to stifle his own laughter); Albano was not hurt and the incident airs on the October 15 broadcast of WWF All-Star Wrestling. Also during the same event, The Grand Wizard makes his last live appearances in his lifetime; squash matches with him appearing in the corner for Sgt. Slaughter and The Masked Superstar will air on All-Star Wrestling the weekend of October 22, 10 days after The Grand Wizard's death, as his passing will not be announced for another week.
- 17 - In what has become one of wrestling's most iconic matches, "Superfly" Jimmy Snuka leaps off the top of a 15-foot high steel cage onto a prone Magnificent Muraco following their match at New York City's Madison Square Garden; the leap happens shortly after Muraco had been knocked outside the cage and inadvertently won their match, thus successfully defending his WWF Intercontinental Championship. The match is aired live on the USA Network, and in attendance at the show were future wrestling stars The Sandman, Mick Foley, Tommy Dreamer, and Bubba Ray Dudley; all of them cited this match as a major reason they decided to pursue professional wrestling.
- 23 - Tommy Rich defeats Buzz Sawyer in a bloody steel cage match in Atlanta, Georgia to climax their 18-month feud; this event was dubbed The Last Battle of Atlanta and was a precursor to Hell in the Cell, as the steel cage for this match had a top
- 29 - The sudden death of The Grand Wizard is acknowledged on the WWF's syndicated television programs, a rare break of kayfabe in wrestling at the time. A storyline was arranged in the following weeks, speculating who would take over as on-screen manager of wrestlers he was paired with on television.
