Stanhope Gardens is a suburb of Sydney, in the state of New South Wales, Australia. Stanhope Gardens is located 39 kilometres north-west of the Sydney central business district in the local government area of City of Blacktown. Stanhope Gardens is part of Greater Western Sydney area.

History – John Hillas (1768–1837) arrived in Australia in 1801 and received two land grants (in 1801 and 1804) on the Windsor Road. The second of these, of 150 acres, he named “Stanhope Farm”. He established an inn, the “Stanhope Arms” on Windsor Road to cater for the traffic between the Macquarie Towns and Paramatta.

By 1856 the Pearce family owned “Stanhope Farm”. In 1928 Jack Peel bought “Stanhope Farm” and called it “Stanhope Park Dairy”.

In 1973 the New South Wales Housing Commission compulsorily resumed Stanhope Park Dairy.

The suburb name reflects these early properties. Stanhope Gardens Estate opened in 1995 and was formally recognised as a suburb in 1996.

When Stanhope Gardens was first being developed into what it is today, it was called “Irish Town”, Kellyville and Parklea. A petition was sent around with most people voting to keep Stanhope in the name, becoming Stanhope Gardens.

Newbury Estate – a master-planned estate – now occupies a large part of the suburb of Stanhope Gardens. Planned by Landcom, in 1999 Newbury Estate won the Royal Australian Planning Institute Award for Excellence in Plan Making – Urban Planning.

Commercial arae – Stanhope Village is a sub-regional shopping centre anchored by a Coles supermarket, Liquorland and Kmart, plus 40 other specialised retail, service, fashion and food outlets. It is presently (July 2013) being redeveloped and extended.
