The Wilge River (iKuthu) is a river in Mpumalanga and Gauteng provinces, South Africa. It is a tributary of the Olifants River.
The Wilge River has its origin about 15 km WNW of Leandra, in the highveld grasslands between this town and Springs, Gauteng.[2] It flows roughly northwards until it is joined by its main tributary, the Bronkhorstspruit, that joins its left bank about 25 km downstream of Bronkhorstspruit town. Then it flows in a northeastern direction until it joins the Olifants about 12 km upstream from the head of the Loskop Dam reservoir.[3]
Other tributaries of the Wilge are the Kendal and the Devon River.[4]
