The 1962–63 Ranji Trophy was the 29th season of the Ranji Trophy. Bombay won the title defeating Rajasthan in the final. The tournament was severely impacted by the Chinese Aggression of 1962. Services and Railways pulled out of the tournament after playing one game each. Being so close to the action Assam and Odisha had to pull out of the tournament. When the ceasefire was ordered, the invaders were only a few kilometres away from Tezpur, which was the headquarters of Assam cricket. Bihar played one match and then closed their season as most of their players were employed in firms and factories which were pressed into defence production.
