The MPG Ateneo Alumni Invitational (MAAI) is the alternative second conference for teams and players of the Ateneo Basketball League (ABL). The fundamental difference from the ABL is that non-Ateneans are allowed to participate in the MAII. In essence, it gives ABL players an opportunity to share the ABL experience with their non-Atenean friends and team mates.

The MAAI began in 2005 as one of the tournaments of the Gillette MBL. From 20 teams in 3 divisions in 2005, the 2006 season has drawn 42 teams grouped into 7 divisions. The tournament will be held from July 22 to September 10, 2006.
