This is a list of various things that took place in 2012.
- 21 - Gold Rush Pro Wrestling is founded in Pacifica, California.
- 1 - Next Level Pro Wrestling was founded in Montreal, Quebec, Canada.
- 20 - WWE has every champion a fan-favorite, this is the first time this has happened since 2007.
- 23 - The Brothers of Destruction is reunited
- 31 - Ownership of the National Wrestling Alliance brand and trademarks passes from previous owner Pro Wrestling Organization LLC to a new company, International Wrestling Corporation LLC.
- As a result of the change of ownership of the NWA to the International Wrestling Corporation, several promotions previously affiliated with the NWA, including Championship Wrestling from Hollywood, Pro Wrestling Revolution, Wisconsin Pro Wrestling and Mach-One Pro Wrestling, withdraw their memberships and leave the NWA. The affected promotions' decision to terminate their NWA memberships stemmed from, among other issues, not being happy with certain terms and conditions contained in new licensee agreements sent out to NWA members and associate promotions. 
- 10 - During a live telecast of Monday Night RAW, color commentator Jerry Lawler suffers a legitimate heart attack, while helping Michael Cole call a match between Team Hell No (Kane and Daniel Bryan) and The Prime Time Players. Cole summoned paramedics to the announcer's table when Lawler missed a cue, and the only deviation from the planned match was referee Charles Robinson and wrestler Titus O'Neill signaling for aid after observing what was going on at ringside. Cole, immediately scrapping his heel persona, provides live updates and wishes Lawler a speedy recovery, and is able to tell the audience that Lawler had been revived, was on his way to the hospital and was receiving the best care. (Incidentally, Lawler had wrestled earlier in the evening and had not complaining of illness before collapsing.) Lawler undergoes an angioplasty the next day and a week later returns home; he will return to work in mid-November. The situation makes national news, and Cole -- falling back on his days as a reporter for CNN -- is lauded for his expertise and breaking news reporting abilities.
- NWA All Star Wrestling (not the long-defunct Canadian promotion of the same name, but a Virginia-based promotion) becomes the latest promotion to drop out of the NWA.

- 30 - Bobby Jaggers (renal failure and complications from Hepatitis C)
- 22 - Rip Hawk
