The 1927 Chatham Cup was the fifth annual nationwide knockout football competition in New Zealand. The competition was run on a regional basis, with five regional associations (Auckland, Wellington, Manawatu, Canterbury, and Otago) each holding separate qualifying rounds. Teams taking part in the final rounds included Ponsonby (who defeated Auckland Thistle in the Auckland regional final), St. Andrews (Manawatu), Northern (Dunedin), Nomads (Christchurch), and Wellington Marist (who defeated YMCA in the Wellington regional final).
