The Wilge River (Afrikaans: Wilgerivier, meaning "willow river") is a tributary of the Vaal River in central South Africa. This river is important as part of the Tugela-Vaal Water Transfer Scheme where water is transferred from the Tugela River basin to the Vaal River basin.

The largemouth yellowfish is present in the waters of the Wilge River, reaching quite a large size.
