Ballajura was an electoral district of the Legislative Assembly in the Australian state of Western Australia from 1996 to 2005.
Ballajura was a north-to-south elongated electorate squeezed between Alexander Drive and Beechboro Road.
The district contained the suburbs of Ballajura, Malaga, Noranda and the lightly populated Cullacabardee.
The seat was won by Liberal candidate Rhonda Parker, previously the member for Helena, which had been abolished.
The redistribution ahead of the 2008 state election saw Ballajura abolished and divided between the new districts of Morley and West Swan.
