The Nike Summer League is a defunct pre-season collegiate basketball tournament in the Philippines sponsored by Nike. Its first season started in 2006. The tournament was last held in 2009. Games were telecast on TV by Studio 23.
Its format consists of dividing the teams into 4 groups, in which a single round robin is played against other teams of the same group to determine the quarter finalists. The top two teams from each group comprise the 8 quarter finalists. A knockout game is played between the top seed of group A and the lower seed of Group D and vice versa. The same happens between group B and C quarter finalists. The tournament goes on until 1 team becomes champion.
