Rooty Hill is a suburb of Sydney, in the state of New South Wales, Australia. Rooty Hill is located 42 kilometres (26 mi) west of the Sydney central business district, in the local government area of the City of Blacktown and is part of the Greater Western Sydney region.

Rooty Hill was broadly inhabited by the Darug people before European settlement.

The earliest exploration of the area was led by Captain Watkin Tench in 1789. The origin of this name puzzled historians for many years because the clue lay not in Blacktown City but on Norfolk Island. Governor Philip Gidley King had been in charge of the first settlement there in early 1788 and had noted that the hillside where he had built his Government House had been difficult to dig owing to the amount of tree roots beneath the surface. The hill on Norfolk became known as Rooty Hill and the name is now official. When King returned to New South Wales he built the headquarters for his government reserve of 1802 at the foot of a hill that reminded him of the Norfolk Island Rooty Hill and used the same name. The name Rooty Hill first appeared on a map in 1803.

The early development of the area came when Captain William Minchin was given a grant of 400 hectares (1,000 acres) in 1819, leading to the development of the Minchinbury estate. Dr Charles McKay purchased the estate in 1859 and subdivided it in the 1880s. Afterwards, the Watts family built Watts Cottage in Watt Street. It combines Italianate elements with a bullnose verandah and is almost unique in the Blacktown Municipality. It is locally heritage-listed.

In 1890, the Imperial Hotel was built north of the railway station by F.J. Weston. It was intended to cater for the crowds who attended the greyhound racing at Lamb's Woodstock Coursing Track at Plumpton. By the early 1970s it had become semi-derelict, but was acquired by a local dentist in 1977. It reopened in 1982 and is now state heritage-listed.

In 1891, the Pioneer Memorial Church, located on Rooty Hill Road South, was built on land donated by Dr Charles McKay. It was originally a Baptist church, but was later acquired for the Presbyterian community by James Angus, owner of the Minchinbury estate from 1895. It is still in use and is locally heritage-listed.

In 1902–1903, the School of Arts, located in Rooty Hill Road South, was built by the residents for community activities. The foundation stone was laid 1 November 1902, by Miss Angus, daughter of James Angus. It is locally heritage-listed.

On 13 April 1916, James Angus was killed at Rooty Hill railway crossing, as a result of being hit by that morning's express train. He was survived by his wife, his son James (of Adelaide), his son John (a pastoralist in New South Wales) and his daughter, who by that time was the widow Mrs Fleming.

The name of James Angus is preserved in Angus Avenue; Charles McKay's name survives in Dr Charles McKay Reserve; the name of the Evans family, who built Fairholme, survives in Evans Road. Fairholme, now part of the St Agnes Catholic High School, is locally heritage-listed.

During and following World War II, Australia had realised its demographic crisis in simply not having enough people, exacerbated by the threat of Japanese invasion. In response, Australia allowed immigration from more and more nations as previously restricted by the White Australia policy. In 1973, the Whitlam government effectively abolished the White Australia policy, meaning people would not be denied immigration due to their nationality. Notably, this allowed immigrants from Asia to come in, and in the ensuing decades, especially from the 1990s-2010s, many Filipinos, Indians, Pakistanis, Polynesians and Chinese immigrants populated Rooty Hill, rendering the suburb in the multicultural state it is in today.

In 1964, the Rooty Hill RSL (now known as West HQ) was built, and over time turned into the largest licensed club in New South Wales, serving as a hub for entertainment, fitness and lifestyle. Dubbed by some as the "Vegas of the West", the RSL also has Western Sydney's largest gym, five star accommodation and conference facilities. Currently, the RSL has approximately 50,000 members. West HQ also has Sydney Coliseum Theatre, intended to somewhat be "Sydney Opera House of Western Sydney".
