The 1925 Chatham Cup was the third annual nationwide knockout football competition in New Zealand.
The competition was run on a regional basis. Each region held its own contest to find a regional champion, with these then being grouped into four regional associations (Auckland, Wellington, Canterbury, and Otago), each of which was represented in semi-finals by one team, followed by northern and southern semi-finals and a national final.
