Baseball in the University Athletic Association of the Philippines (UAAP) has always been held as a men's tournament.

Six teams are participating in the seniors division while there are four teams in the juniors division.

Baseball is among the initial sports contested at the UAAP since its inception in 1938.^[1] Baseball was added as a demonstration sport for the junior division in Season 74 (2011–12) as there were only three teams participating. In Season 80 (2017–18), it was elevated to a regular sport since the number of participating teams increased to four.^[2]
