The ACUI Collegiate Pocket Billiards National Championship, in recent years known more specifically as the ACUI Collegiate Nine-ball National Championship, was an amateur United States annual pool competition for university and college students, organized by the Association of College Unions International (ACUI). It was founded in 1937,[1] and was one of ACUI's longest-running programs. In June 2020, the ACUI made the decision to discontinue their National Collegiate Pocket Billiards program.[2]
