Kellyville Ridge is located 41 kilometres north-west of the Sydney central business district in the local government area of City of Blacktown.

The suburb takes its name from the ridge, the main geographical feature of vertical significance in the northern part of the area.

Population estimates by the Australian Bureau of Statistics indicated that Kellyville Ridge and surrounding neighbourhoods had the largest growth in 2013–14 in Sydney.

The area experienced one of metropolitan Sydney's fastest growth rates, with a 9 per cent increase in population in 12 months.

It is located on the western perimeter of the suburb at the intersection of The Ponds Boulevard and Riverbank Drive.

[5] Stanhope Village is a shopping centre adjacent to the suburb, with Aldi, Coles, Kmart and other specialised retail, service, fashion and food outlets.

CDC NSW services take around 1 hour to Sydney CBD from Kellyville Ridge.

The North West Rail Link which opened 26 May 2019 – now known as Sydney Metro Northwest – provides high frequency services to Kellyville Ridge, linking it to Sydney CBD in around 50 minutes, which will drop to 40 minutes on completion of the second stage of the project.
