Tammin is a town in the central agricultural region of Western Australia, 184 kilometres (114 mi) east of Perth[2] and midway between the towns of Cunderdin and Kellerberrin on the Great Eastern Highway.

The town is a receival site for Cooperative Bulk Handling.

[3] It also serves as a stop on the Prospector and MerredinLink rural train services.

The railway to Southern Cross was constructed through the area in 1894–95, and Tammin was one of the original stations when the line opened in 1895.

[4] 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.
