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 20km (10miles) 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.
