The Wimmera River, an inland intermittent river of the Wimmera catchment, is located in the Grampians and Wimmera regions of the Australian state of Victoria. Rising in the Pyrenees, on the northern slopes of the Great Dividing Range, the Wimmera River flows generally north by west and drains into Lake Hindmarsh and Lake Albacutya, a series of ephemeral lakes that, whilst they do not directly empty into a defined watercourse, form part of the Murray River catchment of the Murray-Darling basin.

Dimboola is a town in the Shire of Hindmarsh in the Wimmera region of western Victoria, Australia, 334 kilometres north-west of Melbourne.
