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, Republic of China 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.
