Mukinbudin is a town in the North Eastern Wheatbelt region of Western Australia, approximately 293 kilometres (182 mi) east of Perth and 80 kilometres (50 mi) north of Merredin near Lake Campion. It is the main town in the Shire of Mukinbudin. At the 2006 census, Mukinbudin had a population of 281.
The present Shire of Mukinbudin was settled by pastoralists who in the 1870s took up large leases in excess of 20,000 acres (81 km2) to run sheep and by sandalwood cutters and miners en route to the goldfields. In 1910 the first of the farmers arrived to commence wheat growing on their 1,000 acres (4 km2) block and it was some time before they added stock to what had been entirely a wheat growing enterprise. An extension of the Mount Marshall railway line to Mukinbudin and Lake Brown was approved in 1922 and opened in October 1923. The townsite was gazetted in 1922.
In 1932 the Wheat Pool of Western Australia announced that the town would have two grain elevators, each fitted with an engine, installed at the railway siding.
The surrounding areas produce wheat and other cereal crops. The town is a receival site for Cooperative Bulk Handling.
The town was hit by a wild storm in February 2011 and was lashed by strong winds with gusts over 125 km/h, large hailstones and experienced some flooding. Dozens of power poles and hundreds of trees were blown over and parts of roads were washed away.
