The Grays River is a tributary of the Tekapo River in the Mackenzie Basin of New Zealand. It flows southwest for 25 kilometres (16 mi), joining the larger river southeast of Lake Pukaki.

It should not be confused with the Gray River, a small tributary of the Awatere River in Marlborough, nor with the much larger Grey River on the South Island's West Coast.
