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

It is a mixture of suburbia and hinterland, falling inside the Metropolitan Region Scheme and running along most of its southern and eastern boundary.

The seat was radically redistributed ahead of the 2008 state election, with 15% of the voters in the redrawn district coming from its former configuration.

Simpson served as the MP for Darling Range until his defeat by Barry Urban at the 2017 state election.

In May 2018, Urban resigned from parliament as the privileges committee recommended his expulsion over a series of false claims of his credentials.
