The Fr. Bellarmine Baltasar Gymnasium (also known as the San Beda College Alabang Gym) is a gymnasium within San Beda College Alabang in Muntinlupa, Philippines. It has a seating capacity of 1,200 for sporting events and a full house capacity of 5,560.
Within the gymnasium are two full-sized basketball courts, volleyball courts and an event stage. It is also the location of the school's athletic offices.[1] With the assumption of Dom Clement Ma. H. Roque, OSB as the eighth rector-president, the gymnasium was renovated. During the 2015–16 school year, the San Beda College Alabang Gym was officially renamed in honor of the school's fourth rector-president, Fr. Bellarmine Baltasar, OSB, who was the rector-president of the school from 1985 to 1995.
The gymnasium underwent its first major renovation in 2019 under the leadership of Rev. Fr. Gerardo Ma. De Villa, OSB, in preparation for the school's hosting of the NCAA South Season 21.
It is the main athletics academic facility, used for most in-school events, including non-athletic ones. This includes Moving Up Ceremonies, Cultural Event Shows, Integration, the famous Batch Cheering, and other inter-school activities. The school's annual Bodega Sale was held here until 2015 when their Baratillo Sale replaced it from 2016 onwards.
