The 1931 Chatham Cup was the ninth annual nationwide knockout football competition in New Zealand.
The competition was run on a regional basis, with six regional associations (Auckland, Walkato, Wellington, Manawatu, Canterbury, and Otago) each holding separate qualifying rounds.
This was an improvements over previous years, but still a tiny number considering that 514 teams were affiliated to the regional associations nationwide.

Nomads defended stoutly to keep the scores tied until full-time, but in the first period of extra time both H., Donaldson and Arthur Spong scored for the Auckland team.
