Hillarys is an electoral district of the Legislative Assembly in the Australian state of Western Australia.

Politically, it is typically a safe Liberal seat but Caitlin Collins won it for the Labor Party for the first time at the 2021 election.

The district includes the suburbs of Hillarys, Padbury, Kallaroo, Mullaloo, Beldon and Craigie.

The district was first contested at the 1996 state election, essentially replacing the seat of Whitford.

It was held by Liberal MP Rob Johnson from its creation until his 2017 defeat, after resigning from the party to sit as an independent.
