The electoral district of Wimmera was an electoral district of the Legislative Assembly in the Australian state of Victoria. It was defined initially as "Bounded on the West by the Boundary Line of Victoria and South Australia; on the North by the River Murray; on the East by a Line to Lake Bael Bael, thence by the River Avoca to its Source; and on the South by the Boundaries of the Counties of Follett, Dundas and Ripon". In the Electoral Act of 1877 established the seat as a two-member constituency, reabsorbing Crowlands.
