Clay Island Lighthouse was built in 1832 and deactivated in 1892 and was located at the entrance to the Wicomico River on the Eastern Shore of the Chesapeake Bay at the confluence of Nanticoke River, Fishing Bay, and Tangier Sound. It was a small 1-½ story building with the tower on the roof. Sharkfin Shoal Light replaced this lighthouse in 1892 and the building later collapsed. No trace of the lighthouse remains.
