The Little Opawa River is a river of the south Canterbury region of New Zealand's South Island. It flows generally east from a ridge 20 kilometres (12 mi) southwest of Fairlie, joining with its southern neighbour, the Ōpaoa River very close to their joint outflow into the Tengawai River, close to the settlement of Albury.
