Wrestling Hinokuni (レスリング火の国, Resuringu Hinokuni) was a professional wrestling event promoted by New Japan Pro-Wrestling (NJPW). The event was established in 2015 and took place in late April between the larger Invasion Attack and Wrestling Dontaku events. The event was held in Mashiki, Kumamoto and its name referred to the nickname of Kumamoto Prefecture, "Land of Fire" (火の国, Hinokuni). The 2016 event was canceled due to the 2016 Kumamoto earthquakes. In 2017, the event was replaced by Wrestling Toyonokuni, taking place in Beppu, Ōita.

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

The first Wrestling Hinokuni took place on April 29, 2015, at the Grand Messe Kumamoto in Mashiki, Kumamoto, and aired worldwide on NJPW World. The event featured nine matches, three of which were contested for championships. Wrestlers representing the National Wrestling Alliance (NWA) took part in the event with both the NWA World Heavyweight and NWA World Junior Heavyweight Championships being defended. In the first title match, NWA representative Steve Anthony successfully defended the NWA World Junior Heavyweight Championship against NJPW's Jushin Thunder Liger. This was a rematch from a match in Las Vegas earlier in the month, where Anthony also defeated Liger to capture the title. The second title match saw NJPW's Hiroyoshi Tenzan make his second successful defense of the NWA World Heavyweight Championship against NWA's Big Daddy Yum-Yum. Several matches at the event also built to matches taking place at Wrestling Dontaku 2015 the following week. One of these matches saw Bullet Club's Doc Gallows, Karl Anderson and Kenny Omega defeat Alex Shelley, Tetsuya Naito and Tomoaki Honma in a six-man tag team match in the buildup to an IWGP Junior Heavyweight Championship match between champion Omega and challenger Shelley.
