Marchagee is a small townsite located 243 km north of Perth in the Mid West region of Western Australia.

A reserve for travellers was kept aside in the area in 1876, and the name recorded by the surveyor was Marchagee Well.

In 1899 the Midland Railway Company established a station at Marchagee.

Some large lots were surveyed for agricultural purposes in 1906, and the townsite was gazetted in 1927.

The town is a receival site for Cooperative Bulk Handling.
