The Division of Wimmera was an Australian electoral division in the state of Victoria. It was named after the Wimmera region in which it was partially located. The division was proclaimed in 1900, and was one of the original 65 divisions to be contested at the first federal election.

It originally encompassed Mildura, Swan Hill and Warracknabeal. In 1949, the Division of Mallee took the seat's northern area.

By the time the seat was abolished on 31 October 1977, it had drifted south and grown smaller to only include Ararat, Horsham and Maryborough. It become part of the Division of Mallee, reuniting the two divisions.
