The Tūranganui River of the Wellington Region of New Zealand flows through the south Wairarapa from its source in the Aorangi Range to reach the Ruamahanga River shortly before the latter's outflow into Palliser Bay.

In December 2019, the approved official geographic name of the river was gazetted as "Tūranganui River".
