Gussage All Saints is a village and parish in the county of Dorset in southern England. It lies within the East Dorset administrative district of the county, about 8 miles north-east of the town of Blandford Forum. It is sited by the side of a small stream in a shallow valley on the lower dip slope of Cranborne Chase. Ackling Dyke, a disused Roman road, crosses the valley to the northwest, and forms the parish boundary at that point.
