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. Later, a small portion of the district was split off to create Ga Central Municipal Assembly on 28 June 2012; thus the remaining part has been retained as Ga South Municipal District. However on 15 March 2018, the northern part of the district was split off to create a new Ga South Municipal District, with Ngleshie Amanfro as its capital town; thus the remaining part has been renamed as Weija Gbawe Municipal District, with Weija as its capital town.
