Koongamia is a suburb of Perth, Western Australia, located in the City of Swan local government area.
The suburb was developed as a State Housing commission suburb, and had a brief time (1960-1962) as a location on the Perth metropolitan railway system, utilising a small portion uphill from Bellevue railway station on the track of the former Mundaring Loop railway line which was suspended since 1954 and had not been officially closed.
