Diggers Rest (formerly Diggers' Rest) is a suburb in Melbourne, Victoria, Australia. It is 28 km (17 mi) and 29 minutes north-west of Melbourne's Central Business District, located within the Cities of Hume and Melton local government areas. Diggers Rest recorded a population of 5,669 at the 2021 census.

Diggers Rest lies on the Old Calder Highway, near the Calder Freeway.

Diggers Rest began life as a stopping place on the road to the Bendigo goldfields, with the Post Office opening on 18 June 1860. Caroline Chisholm started a women's shelter in the area. The town grew in the 1870s and 1880s and became a postal village with a general store, post office, weighbridge, mechanics' institute and a chaff mill. The Diggers Rest Hotel was built by 1854, and later enlarged, and became an important stopping place on the route to the goldfields. It was severely damaged by fire.

Diggers Rest is referred to as being famous for being the location of the first controlled powered flight of an aeroplane undertaken in Australia. The flight was performed by Harry Houdini on the 18th of March, 1910. The only café in town is named in his honour.

To the north of Diggers Rest township within the locality is the former township known as Aitken's Gap, The Gap or Buttlejorrk.

The four Sunbury Pop Festivals were held on the same 620-acre (2.5 km) private farm along Jacksons Creek, on the southern outskirts of Sunbury, between Sunbury and Diggers Rest. The property was owned by farmer and local identity George Duncan, and the property has become known in the district over the years simply as "Duncan's farm". The entrance gates to the Sunbury Pop Festivals were off Watsons Road. Also because of its proximity (2 km; 1.2 mi) to the smaller township of Diggers Rest, many of the attendees who traveled to Sunbury by train, actually alighted at Diggers Rest railway station, and not Sunbury.

Diggers Rest contains a general store, a primary school and a CFA fire station, along with three large recreation reserves. Sporting groups in Diggers Rest include Diggers Rest Football Club, which play in the Riddell District Football League.
