Riverstone is an electoral district of the Legislative Assembly in the Australian state of New South Wales.

It has been represented by Warren Kirby of the Australian Labor Party since the 2023 New South Wales state election.

[1][2] Much of the electorate is situated in the growing north-west sector, which has been poorly served in transport, health and police resources.

Although ancestrally a Labor seat, changing demographics in the eastern portion of the seat (Glenwood, Parklea, Acacia Gardens, Stanhope Gardens, Kellyville Ridge, The Ponds, Rouse Hill) suggested a long-term Liberal trend in voting patterns.

[4] On its current boundaries, Riverstone takes in the suburbs of Acacia Gardens, Angus, Grantham Farm, Kellyville Ridge, Nirimba Fields, Parklea, Richards, Riverstone, Schofields, Stanhope Gardens, Tallawong, The Ponds and parts of Glenwood, Marsden Park, Quakers Hill, Rouse Hill and Vineyard.
