This is a partial list of conference champions from the 1948 season. Each of the eight geographical districts chose, by various methods, the team that would represent them in the NCAA Tournament. Conference champions had to be chosen, unless all conference champions declined the bid.[1]
The 1948 season marked the second NCAA Baseball Tournament, which consisted of eight teams divided into two brackets by region. The Eastern playoff was held in Winston-Salem, North Carolina, while the Western playoff was held in Denver, Colorado. Unlike the previous year, a double-elimination format was used. The winner of each bracket advanced to the College World Series in Kalamazoo, MI, where Southern California defeated Yale in a best of three series.
