Glenwood is located 40 kilometres west of the Sydney central business district in the local government area of the City of Blacktown. Glenwood is part of the Greater Western Sydney region and is considered to be part of the Hills District.
Glenwood takes its name from an historic property in the area, named ‘Glenwood Park’ in the 1940s, but previously known as Norfolk Vale (1846-1882), and Sorrento (1882-1941). It was formally recognised as a suburb in 1996.
It is noted as the first site to be developed within the Rouse Hill Development area.
The M2 Hills Motorway runs along the southern border of the suburb and provides a link to the Westlink M7 Motorway. Old Windsor Road borders the suburb to the east and Sunnyholt Rd borders the suburb to the west and north.
Hillsbus provides services to Rouse Hill, Parramatta and Sydney CBD whilst Busways provides regular services to Norwest Business Park, Blacktown, Castle Hill and Macquarie Park.
The suburb is serviced by Burns and Sorrento stations on the Blacktown-Parklea T-way, and Burns, Balmoral, Celebration, Meurants and Norbrik stations on the Rouse Hill- Parramatta T-way.
Schools in Glenwood include Glenwood High School, Caddies Creek Public School, Parklea Public School and Holy Cross Primary School.
