Berkshire Park is a suburb of Sydney, in the state of New South Wales, Australia. It covers 19.3 square kilometres (7.5 sq mi) within the local government area of City of Penrith. The suburb has a diverse range of activity, including a pet cemetery, correctional facility, nature reserve, waste management centre and a racehorse education centre.

The suburb's name is believed to have come from the English county of Berkshire. The land was given to Richard Rouse as a land grant in 1838. Rouse may have chosen this name because he had been married in North Hinksey, which was then part of Berkshire.

Berkshire Park Post Office opened on 1 May 1936 and closed in 1961.

There is a large recreational area located on 6th Rd, Berkshire Park. Part of this area is a reserve for public use, with seating areas and a children's playground. There is also a public hall and the station of the Berkshire Park Rural Fire Brigade, a brigade of the NSW Rural Fire Service.
