Heatherton is a suburb in Melbourne, Victoria, Australia, 19 km south-east of Melbourne's Central Business District, located within the City of Kingston local government area. Heatherton recorded a population of 2,826 at the 2021 census.

The suburb has a low population for a metropolitan suburb. It is predominantly open space: market garden, golf courses (the Kingston Heath Golf Club and the Capital Golf Club) and the large Karkarook Park.

As part of the Melbourne Sandbelt, the area has been subject to significant sand mining in the past, though many extraction sites have now passed to other uses. Heatherton Post Office opened on 6 May 1885, but closed in 1973.

The Kingston Centre, a major regional Aged Care and Rehabilitation facility, is located on Warrigal Road. The site was originally the Melbourne Benevolent Asylum (where construction began in 1909). A 2 ft (610 mm) narrow gauge tramway was constructed from the railway at Cheltenham to the building site. A large proportion of the grounds of the Kingston Centre were sold in the 1990s to the developer Mirvac, who built the 500 homes of the Heath estate between 2000 and 2009.
