Smith Island is a collection of three distinct island communities – Tylerton, Rhodes Point, and Ewell, Maryland – on the Chesapeake Bay, on the border of Maryland and Virginia territorial waters in the United States. The island is the last inhabited island in Maryland that is not accessible by vehicle. Most of the islands are eroding due to tidal currents and sea level rise; a study conducted in 2008 by the DNR reported that Smith Island is expected to completely erode by 2100 if no action is taken.
