Mount Cottrell is a town in Victoria, Australia, 31 km west of Melbourne's Central Business District, located within the Cities of Melton and Wyndham local government areas. Mount Cottrell recorded a population of 569 at the 2016 Census.
It is named after Anthony Cottrell, a member of the Port Phillip association who was allotted the land by the company in about 1835–36. The original "No.10" hut was located about 1.5 km north of the Mount Cottrell summit.
The town consists of mainly privately owned open land. It is named after the 200m high mountain it encompasses, called Mount Cottrell. Mount Cottrell is a volcanic cone formed by the radial eruption of numerous lava tongues, the most massive of the Werribee Plains volcanoes. The mountain was purchased by Melton Council in 2007 to preserve the significant geological and flora and fauna values on the site.
Mount Cottrell Post Office opened on 1 January 1866, closed in 1895, reopened in 1902 and closed again in 1958.
