Perth was an electoral district of the Legislative Council of Western Australia from 1870 to 1890, during the period when the Legislative Council was the sole chamber of the Parliament of Western Australia.
It then ran south-east out to near present-day Ashendon, before going north-east to Mount Dale, which was the easternmost point within the district.
Perth's northern boundary ran north-west from Mount Dale to Belmont (on the Swan River), then north by west to Lake Gnangara, and finally north to a due east line intersecting Nowergup Lake.
In total, eight men represented the district between 1870 and 1890, the longest-serving of which was Sir Luke Leake (from 1870 to 1886).
Several of the district's representatives went on to serve in the Legislative Assembly after the advent of responsible government in 1890.
