Rosemeadow is a suburb of Sydney, in the state of New South Wales, Australia. Rosemeadow is located 56 kilometres south-west of the Sydney central business district, in the local government area of the City of Campbelltown and is part of the Macarthur region.

Rosemeadow owes its name to early settler Thomas Rose, who in 1818 bought a farm called Mount Gilead which covered parts of modern-day Rosemeadow and neighbouring Gilead. Rose was a baker and publican as well as a farmer, building a mill on his property and a couple of large dams which helped him and his neighbours survive the drought of 1829.

The area remained farmland until the mid-1970s when Sydney's urban sprawl reached it and the suburb was officially named in 1976. The Rosemeadow public housing estate is an example of the American Radburn design for public housing which turns houses around so they back on to streets with the fronts facing each other. This design has been criticised in Sydney as contributing to social problems and following an incident of street violence in 2009 orders were made to partially demolish the estate. Since the partial demolishing of the suburb, the streets have begun to be renamed.

Streets in Rosemeadow are named after characters from the works of William Shakespeare, such as:

• Hamlet Crescent
• Macbeth Way

• Romeo Crescent

• Cleopatra Drive

• Desdemona Street
