West Coast Region

 is a local government region of New Zealand. It adjoins the central section of the west coast of the South Island, the Tasman Region to the north-east, the Canterbury Region to the south-east, and the Otago Region to the south.

Chief population centres are Greymouth (the regional council headquarters), Westport, and Hokitika.

The region comprises most of the former Westland Province (1873-1876) and the western part of the Nelson Province (1852-1876).
