Sunyani West District is one of the twelve districts in Bono Region, Ghana. Originally it was formerly part of the then-larger Sunyani District on 10 March 1989; until the northwest part of the district was split off to create Sunyani West District on 1 November 2007 ; thus the remaining part has been retained as Sunyani District. The district assembly is located in the western part of Bono Region and has Odumase as its capital town.
