Tokyo Big 6 Baseball League is an intercollegiate baseball league that features six prominent universities in the Tokyo area. Before the 1936 establishment of the Japanese Baseball League and subsequent growth (after 1950) of Nippon Porfessional Baseball (NPB), the Big 6 League was widely considered the highest level of baseball in Japan.

The six teams play short, eight-weekend seasons in the spring and autumn of each year. Each team plays a short series against each of the five other teams in the league. The series format is similar to a three-game playoff, where the first to two wins is given a series victory. Home field is alternated, and all games are played at Meiji Jingu Stadium. Should a team sweep the first two games, the third game is not played.

The champion of the league is determined by the team with the most series victories. The champion team is given the Emperor's Cup. This is unique in Japan in that the other Emperor's cups are given to national champions in other sports such as Emperor's Cup of Football. The spring champion is allowed to participate in the All Japan University Baseball Championship Series while the fall champion is allowed to compete in the Meiji Jingu Tournament.

The league uses rules that are similar to the National and Central Leagues. The designated hitter rule is not used and the pitcher is required to bat. Also, unlike American university leagues, non-wood bats are banned.
