The South Metropolitan Region was a multi-member electoral region of the Western Australian Legislative Council, located in the southern suburbs of Perth, Western Australia. It was created by the Acts Amendment (Electoral Reform) Act 1987, and became effective on 22 May 1989 with five members who had been elected at the 1989 state election three months earlier. At the 2008 election, it was increased to six members.
The region, along with all other Western Australian Electoral Regions, was abolished in time with the 2025 state election, following legislation passed in November 2021 to create a single, state-wide constituency of 37 members.
The Region was made up of several complete Legislative Assembly districts, which change at each distribution.
Since its creation, the electorate had 16 members. Four of the members elected in 1989 had previously been members of the Legislative CouncilâÂÂClive Griffiths and Phillip Pendal (both South Central Metropolitan), John Halden (North Metropolitan) and Garry Kelly (South Metropolitan).
