The Copland River is a river on the West Coast of the South Island of New Zealand. It flows for 20 kilometres from its headwaters in the Southern Alps to its confluence with the Karangarua River.

The headwaters of the Copland lie only eight kilometres to the south of Mount Cook in a valley overlooked by the peaks of Mt. Sefton and Mt. La Perouse. A popular tramping track follows the river and leads to the Welcome Flat hot springs. The track leads onto the Copland Pass and the Copland Glacier.

The river lies within the Westland National Park.
