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

Following a survey conducted in late 1862 by contractor Frederick Smith of Ararat, a plan for a township in the County of Dimboola was proposed.

The name came from the District Surveyor of the time John George Winchester Wilmot, who had previously lived in Ceylon (now Sri Lanka).

The relationship of the name to this area is suggested to have come from 'Upper Regions Station' where an abundance of fruit trees grew in the garden, many of which were figs.

Paintings of Dimboola landscapes by noted Australian painter Sidney Nolan, who was stationed in the area while on army duty in World War II, can be found in the National Gallery of Victoria.

Distinguished Australian-British physicist Richard Dalitz was born in Dimboola, as was World War II nursing matron Olive Dorothy Paschke.

The formally recognised traditional owners for the area in which Dimboola sits are the Wotjobaluk, Jaadwa, Jadawadjali, Wergaia and Jupagik nations.

[8] Dimboola railway station is served by The Overland passenger rail services between Melbourne and Adelaide, twice weekly in each direction.
