Cape Sable Island, locally referred to as Cape Island, is a small Canadian island at the southernmost point of the Nova Scotia peninsula. It is sometimes confused with Sable Island. Historically, the Argyle, Nova Scotia region was known as Cape Sable and encompassed a much larger area than simply the island it does today. It extended from Cape Negro through Chebogue.
The island is situated in Shelburne County south of Barrington Head, separated from the mainland by the narrow strait of Barrington Passage, but has been connected since 1949 by a causeway. The largest community on the island is the town of Clark's Harbour. Other communities are listed below. At the extreme southern tip is Cape Sable.
