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 are known to have 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).
The final was played at Newtown Park, Wellington - the second of three finals to be held at that venue. In 1928 the final moved to the Basin Reserve, a venue which was used regularly until the 1970s; Newtown Park was not to host the final again until 1989.
In the final, which was noted by contemporary sources as being a dour match, Ponsonby made good use of a stiff Wellington wind in the first half, with goals from Gerry Hunter, Bob Innes, and J. Adshead. In the second half, the wind favoured Northern, who pulled two goals back through A. McDowell and A. McTavish. Northern pressed for the equaliser, spending long periods close to Ponsonby's goalmouth, but the Auckland side's defence held and the survived to win 3-2.
