Greymouth is the largest town in the West Coast region on the South Island of New Zealand, and the seat of the Grey District Council. Its population accounts for 20% of the West Coast's inhabitants.
The town is located at the mouth of the Grey River. It stands on narrow coastal plains close to the foot of the Southern Alps. In clear weather, Aoraki/Mount Cook can be clearly seen to the south from near the town. The mouth of the river divides the town into three areas: Blaketown, close to the river's mouth on the south bank; Karoro, to the southeast, separated from Blaketown by a series of small lakes; and Cobden, formerly a separate town, on the river's north bank.
