Bodallin is a town located around half way between Merredin and Southern Cross in Western Australia.
The town takes its name from the railway siding of this name, established between 1894 and 1897. When gazetted in 1918 the town was spelt Boddalin. This was amended in 1947 to Bodallin.
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.
It serves as a stop on the Prospector rural train service, and is a location of a crossing loop on the railway.
The main industry in town is wheat farming with the town being a Cooperative Bulk Handling receival site.
