The 1988 NBL Finals was the championship series of the 1988 season of Australia's National Basketball League (NBL) and the conclusion of the season's playoffs. The Canberra Cannons defeated the North Melbourne Giants in three games (2-1) for their third NBL championship.
The 1988 National Basketball League Finals started on 14 July and concluded on 7 August. The playoffs consisted of two knockout Quarter finals, two best of three Semi-finals and the best of three game Grand Final series. As the two top teams at the end of the regular season, the Adelaide 36ers and North Melbourne Giants both qualified for home court advantage during the Semi-finals.
The finals series were played earlier than usual due to the 1988 Summer Olympic Games which were held at the time the NBL normally held their finals (September–October).
