Norwest is a suburb of the Hills District within Greater Western Sydney, in the state of New South Wales, Australia, located 35 kilometres north-west of the Sydney central business district. The Norwest Business Park is located within Norwest and the adjacent suburb of Bella Vista and Baulkham Hills. The council chambers for The Hills Shire Council are also located within this suburb.

Norwest was officially proclaimed a suburb on 29 June 2018. Previously, it had been part of the older suburbs of Baulkham Hills and Kellyville.

The Geographical Names Board, in June 2018, amended the suburb boundaries of Kellyville, Baulkham Hills, Bella Vista and Rouse Hill resulting in the creation of two new suburbs named North Kellyville and Norwest.

From 2018 to 2019, in preparation for the Norwest metro station which opened in May 2019, Norwest underwent an urban transformation, building up apartments and commercial retail stores around Norwest Lake, while also transforming what was previously "Coles Norwest" into Norwest Marketown.

Norwest Marketown is a shopping centre featuring a Coles and dozens of specialty stores, small electronic and clothing stores, banks, restaurants and a day care centre.

Norwest features two main residential areas along boundaries of the suburb. Within Norwest, there is a variety of housing including low density housing, townhouses and apartments. Most of the housing within Norwest is close to retail, employment, recreation and transport within the suburb and the neighbouring suburbs of Kellyville, Castle Hill and Baulkham Hills.

The area to the north of the suburb is part of the Balmoral Road release area and is within proximity of roads such as Fairway Drive, Stone Mason Drive and Spurway Drive. This area has a wide range from high rise apartments close to the lake to low density housing to the north of the golf course.

The area to the south of the suburb is located along Barina Downs Road and features mainly low density housing and townhouses, with one apartment complex
