Weija Gbawe Municipal Assembly is one of the twenty-nine districts in Greater Accra Region, Ghana. Originally it was formerly part of the then-larger Ga West District in 2004, until the western part of the district was split off to create the first Ga South Municipal Assembly on 29 February 2008, with Weija as its capital town; thus the remaining part was elevated to municipal district assembly status to become Ga West Municipal Assembly.
