The Klip River is a main tributary of the Tugela River in KwaZulu-Natal, South Africa.

The river originates on the west side of KwaZulu-Natal, initially flows eastward and then swings southward.

It flows into the Windsor Dam, and then into the larger Qedusizi Dam before flowing east again.

For a brief period in the mid-19th century, a Klip River Republic was declared in the area by Boer settlers, before being annexed by the British.
