The 2002 Chatham Cup was the 75th annual nationwide knockout football competition in New Zealand.
Up to the last 16 of the competition, the cup was run in three regions (northern, central, and southern), with an open draw from the quarter-finals on.
The nine eligible National League clubs entered the tournament at the third round stage.
One National League side, Canterbury United, was ineligible, as it was an amalgamated team formed from several clubs within the Canterbury region, each of which competed in the Chatham Cup individually.
The winner of the 2002 Jack Batty Memorial Cup was Leon Birnie of Napier City Rovers.
