The 1965 Chatham Cup was the 38th annual nationwide knockout football competition in New Zealand.
The competition was run on a regional basis, with 18 regional associations holding separate qualification rounds. The winners of each of these qualification tournaments, along with the second-placed team from Auckland, qualified for the competition proper. In all, 104 teams took part in the competition, 33 from the South Island and 71 from the North Island. Note: Different sources record different numbers for the rounds of this competition, with some confusion caused by differing numbers of rounds in regional qualification.
Christchurch City's 19–1 Fifth Round demolition of Timaru's Northern Hearts was the largest known victory in any Chatham Cup match until Metro's 21–0 demolition of Norwest in 1998.
