King of Pro-Wrestling (2012) was a professional wrestling pay-per-view (PPV) promoted by New Japan Pro Wrestling (NJPW). The event took place on October 8, 2012, in Tokyo at Ryōgoku Kokugikan. The event featured nine matches, five of which were contested for championships. This event marked the first time a NJPW PPV could be bought outside Japan, through Ustream. It was the first event under the King of Pro-Wrestling name.

King of Pro-Wrestling featured nine professional wrestling matches that involved different wrestlers from pre-existing scripted feuds and storylines. Wrestlers portrayed villains, heroes, or less distinguishable characters in the scripted events that built tension and culminated in a wrestling match or series of matches.

The opening match saw Manabu Nakanishi return from a back injury and wrestle his first match since June 2011. The second match saw Forever Hooligans (Alex Koslov and Rocky Romero) make their successful defense of the IWGP Junior Heavyweight Tag Team Championship against the Time Splitters (Alex Shelley and Kushida). The event featured two title switches; in the first Low Ki defeated Kota Ibushi to win the IWGP Junior Heavyweight Championship for the third time and end Ibushi's two-month-long reign, while in the second, K.E.S. (Davey Boy Smith Jr. and Lance Archer) defeated Tencozy (Hiroyoshi Tenzan and Satoshi Kojima) to win the IWGP Tag Team Championship for the first time. The event also featured a grudge match between former No Limit tag team partners Tetsuya Naito and Yujiro Takahashi, which was used as a way to write off Naito, who had suffered a knee injury and would have to undergo a reconstructive knee surgery. He would remain sidelined until Dominion 6.22 in June 2013. The event concluded with Shinsuke Nakamura making his second successful defense of the IWGP Intercontinental Championship against Hirooki Goto and Hiroshi Tanahashi his fourth successful defense of the IWGP Heavyweight Championship against Minoru Suzuki.
