The 1939 Chatham Cup was the 16th annual nationwide knockout football competition in New Zealand.
The competition was run on a regional basis, with regional associations each holding separate qualifying rounds.
Teams taking part in the final rounds included Ponsonby, Waterside, Hamilton Wanderers, Western, Millerton Thistle and Mosgiel.
Waterside became the first team to successfully defend the trophy - something they were to again achieve the following year. Sonny Ward became the first player to score in two successive finals.
