Chadstone is a suburb in Melbourne, Victoria, Australia, 14 km (8.7 mi) south-east of Melbourne's Central Business District, located within the City of Monash local government area. Chadstone recorded a population of 9,552 at the 2021 census.

Landmarks include the Waverley Basketball Centre, Jordanville Community Centre and the Matthew Flinders Hotel. Scotchmans Creek runs along Chadstone's southern boundary, the Glen Waverley railway line along the northern boundary, Warrigal Road to the west and Huntingdale Road to the east. The Monash Freeway runs through the suburb.

Many of the houses in the Chadstone area were built in the postwar period using prefabricated concrete produced at the current site of Holmesglen Institute. The houses tend to be quite small, with two to three bedrooms and large blocks. It is relatively common for houses to be demolished and larger houses built to take advantage of the block size.

Chadstone Post Office opened on 8 April 1957 and Chadstone Centre Post Office opened on 3 October 1960. The Chadstone office closed in 1998.

Chadstone was home to Jordanville South Primary School on Baradine Street, which closed down at the end of the school year in 1993. It was also home to Chadstone High School (now closed), and Waverley High School (originally named Holmesglen High School, then renamed Jordanville High School and finally Waverley High School not to be confused with Mount Waverley High School located in Mount Waverley) which closed down in 1996. Chadstone's "Christ Campus" of the Australian Catholic University closed down in the early 2000s, its land being bought by Chadstone Shopping Centre to expand.

Chadstone is a small suburb, with parts previously known as Chadstone being rezoned to be incorporated into Malvern East. Several landmarks such as Chadstone Shopping Centre and the Chadstone campus of Holmesglen Institute of TAFE have retained their original names despite now being technically located in Malvern East. The current Chadstone locality incorporates an area formerly known as Jordanville (even though Jordanville Station is technically in Mount Waverley).

There are two schools in Chadstone, both of which are Roman Catholic Independent schools. They are Salesian College and St Mary Magdalen's Primary School.
