The Kēkerengū River is a small river in the north of Kaikōura District, following a valley formed by the geologically active Kēkerengū Fault, that reaches the sea approximately half way between Blenheim and Kaikōura at the eponymous settlement of Kēkerengū. Parts of the lower reaches of the river are braided shingle, while the upper reaches narrow into a gorge. Near the settlement, a vineyard is planted on alluvial river flats, while pastoral farming is practised further up the valley, with native scrub in the riparian zone in much of the upper reaches of the river. Willows line the river near the settlement.
The river is bridged on State Highway One, and several smaller bridges in the Kēkerengū Valley.
