JSL Cup (JSLカップ or JSLカップ選手権大会) was the original league cup for clubs in the Japan Soccer League, the top level of Japanese football before the creation of the J.
The format varied; sometimes the clubs played small group stages, other times it was an outright elimination, including only the clubs that were not recent promotions to the Second Division.
During the season timeframe change of 1985, the cup was played within the year, a rule that stayed until the advent of the J.
Teams are named using current nomenclature, or last one if they are defunct (denoted in italics).
