The Waiho River (traditionally the Waiau River) is a river of the West Coast region of New Zealand's South Island. It is fed by the meltwater of the Franz Josef Glacier and skirts the main township of Franz Josef to its south, where its river bed is crossed by  on a long single-lane bridge.  Due to changes in rainfall and snow melt, the river's water flow varies greatly. In a severe rain storm on 26 March 2019, the bridge was destroyed after  of rain had fallen. The bridge and one abutment was rebuilt, and the road link reopened after 18 days. The works cost NZ$6m.

Waiho River merges with Docherty Creek just before reaching the Tasman Sea  southwest of Okarito.
