The World Tag League (WORLDタッグリーグ, WORLD taggurīgu) is a professional wrestling round-robin tag team tournament held by New Japan Pro-Wrestling as a spin-off of the popular singles tournament, the G1 Climax. It was created in 1991 as the Super Grade Tag League, as a continuation of a regular tag team tournament held since 1980, gaining the name G1 Tag League (G1タッグリーグ, G1 taggurīgu) in 1999. In 2012, NJPW's new owners, the Bushiroad company, renamed the tournament to its current form. Since the tournament acquired its current name, the winning team earns the right to challenge for the IWGP Tag Team Championship at the following year's Wrestle Kingdom, assuming the team does not hold the title at the time of their victory.
