Macarthur (/məˈkɑːrθər/)[2] originally known as Eumeralla, is a town in the Western District of Victoria, Australia on the Hamilton-Port Fairy Road.

[1] Before British colonisation, the region around Macarthur was occupied by the Worerome killink gundidj clan of the Gunditjmara people.

[3] The formally recognised traditional owners for the area in which Macarthur sits are groups within the Eastern Maar and Gunditjmara peoples,[4] who are represented by the Eastern Maar Aboriginal Corporation (EMAC)[5] and the Gunditj Mirring Traditional Owners Aboriginal Corporation (GMTOAC).

The immense leasehold, named Bolden's run, covered large amounts of land west of the Hopkins River.

The township was laid out near the Eumeralla River by surveyor John Turner, with the first land sales taking place shortly after on 17 July 1857.
