The Global Junior Heavyweight League is a professional wrestling round-robin tournament held by Pro Wrestling Noah. The purpose of the tournament is to determine the promotion's top junior heavyweight wrestler. It was originally designed to be an annual event starting in 2009, but the second tournament did not take place until 2015. The tournament is a two-block round-robin tournament, much like New Japan Pro-Wrestling's Best of the Super Juniors tournament, in which each block's two highest scorers face off in the semifinals. A victory is worth two points, a draw was worth one, and a loss zero; each match has a thirty-minute time limit. Being a professional wrestling tournament, the outcome of the matches and the tournament itself are not determined through pure athletic competition but through pre-determined outcomes to matches.
