Balga was an electoral district of the Legislative Assembly in the Australian state of Western Australia from 1974 to 1977 and again from 1983 to 1989.
The district was based in Perth's northern suburbs and was a safe Labor seat.
At the 1972 redistribution prior to the 1974 state election, the seat of Balcatta, held narrowly by Labor's Brian Burke after a 1973 by-election, was renamed Balga, and Burke won it with an increased majority.
The name Balga would last only one term; the seat was renamed back to Balcatta ahead of the 1977 state election.
Balga was abolished ahead of the 1989 state election, and was replaced by the new seat of Marangaroo, which Cunningham went on to represent.
