Nasa is a village in Ghana in the historic Kingdom of Wala in the current Upper West Region of Ghana.
Prior to the dry season of 1887-1888 Nasa was a very substantial town.
During that dry season it was raided by the forces of the Zabarima (emirate) under the command of Babatu.
This caused a mass exodus of much of the population and left behind a large area outside the village with much urban debris.
Among other buildings destroyed by the forces of Babatu was the town's mosque.
