Sissala West District is one of the eleven districts in Upper West Region, Ghana. Originally it was formerly part of the then-larger Sissala District in 1988; until the western part of the district was later split off to create Sissala West District in July 2004; thus the remaining part has been renamed as Sissala East District. The district assembly is located in the northern/northeast part of Upper West Region and has Gwollu as its capital town.
