Castle Hill is a suburb of Sydney, New South Wales, Australia 30.1 kilometres north-west of the Sydney GPO, in the Hills District. Castle Hill is the administrative centre of the local government area of the Hills Shire and part of the suburb is located in the local government area of Hornsby Shire.

The land that is now called Castle Hill was originally home to the Bidjigal people, who are believed to be a clan of the Dharuk people, who occupied all the land to the immediate west of Sydney. The best-known Aboriginal person from that time is Pemulwuy, a Bidjigal leader who led the resistance movement against settlers, including sacking farms in Castle Hill, before his eventual capture and dispatch by local law enforcement.

The Bidjigal people are today commemorated by Bidjigal Reserve which straddles the suburbs of Castle Hill, Baulkham Hills, North Rocks and West Pennant Hills.

The first European visitors to the district were led by Governor Phillip in April 1791 accompanied by an entourage. Traveling from Parramatta reaching the 'hills' following the Aboriginal trails, which today are overlaid by the Windsor and Old Northern Roads. As Governor he needed to find new country for settlement and farming land for crops so as to feed a struggling infant colony.
