The 1976 Chatham Cup was the 49th annual nationwide knockout football competition in New Zealand.
Early stages of the competition were run in three regions (northern, central, and southern), with the National League teams receiving a bye until the later stages of the competition. In all, 146 teams took part in the competition - a record for the time. Note: Different sources give different numberings for the rounds of the competition: some start round one with the beginning of the regional qualifications; others start numbering from the first national knock-out stage. The former numbering scheme is used in this article.
The final against Eastern Suburbs was a one-sided affair (United had had a harder task in their semi-final against Blockhouse Bay). The South Island side scored four, though the first of these was an own goal by Suburbs' Tom Bell. Norman Moran picked up a brace before the scolring was completed by Mark McNaughton.
