Белгийска волейболна лига (на нидерландски: Volleyballiga A; на френски: Ligue A de volley-ball) е най-високото ниво на състезателни волейболни клубове в Белгия. Създадена е през 1946 г. и се управлява от Кралската белгийска волейболна федерация (FRBVB/KBVB). Лигата се състои от 12 отбора, които играят един срещу друг по системата "всеки срещу всеки" по два пъти. Четирите най-добре класирани отбора в редовния сезон се класират за плейофите, където победителят получава титлата и се класира за Шампионската лига на CEV.
