South Walls is a tidal island or peninsula at the southern end of Hoy in Orkney, Scotland. It is connected to the main body of Hoy, and to the district of North Walls, by a thin neck of land known as the Ayre. Its largest settlement is Longhope, which lies on a long natural harbour of the same name. Both North and South Walls belong to the civil parish of Walls and Flotta.
South Walls is a popular stopping off place for barnacle geese.
