The 1963 ABC Championship was the second edition of the ABC Championship, a tournament which was held by FIBA Asia since 1960. The tournament which was held in Taipei, Taiwan saw eight teams compete (an expansion of one team) in a round-robin tournament with the top four teams qualifying through to the championship round where they played each other again one more time. The bottom four teams would compete in a classification round.
The tournament saw the first tie-breaker matches to be played with Thailand defeating Malaya to book a spot in the championship round. In the championship round, the Philippines and Taiwan finish level with an 8–2 record. This meant that they had to play in a play-off to decide the champion which was played on December 3. In that final match, the Philippines would claim their second title defeating Taiwan, 99–71. Third was South Korea who had defeated the play-off teams at least once during the tournament.
