The Akatarawa Valley is a valley in the Tararua Range of New Zealand's North Island. It provides a link from the upper reaches of the Hutt Valley to Waikanae on the Kapiti Coast through rugged hill country. The valley is lowly populated and contains the localities of Reikorangi and Cloustonville. At the Hutt Valley end, the Akatarawa Valley is rugged and the Akatarawa River flows through it. The terrain is less difficult at the Kapiti end, where the Waikanae River flows through part of the valley on its route from its headwaters in the Tararuas to the Tasman Sea, and is met in the valley by tributaries such as the Ngatiawa River and the Reikorangi Stream.
