Mount Desert Light is a lighthouse on Mount Desert Rock, a small island about 18 nautical miles (33 km; 21 mi) south of Mount Desert Island, in the U.S. state of Maine. While the first light station was established in 1830, the current lighthouse was built in 1847. It was listed on the National Register of Historic Places as Mount Desert Light Station in 1988. It is currently owned and operated by the College of the Atlantic, located in Bar Harbor, Maine.
