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, and is part of the US state of Maine. The lighthouse was first established in 1830.
- 1847 Present structure built, designed by Alexander Parris
- 1858 Bell tower, bell, new lantern, and 3rd order Fresnel lens installed
- 1889 Fog bell replaced by a steam whistle
- 1892 Current keeper's house built
- 1931 Electrified with two generators
- 1977 Automated
- At about the same time the Fresnel lens was replaced by an aero-beacon and the lantern was removed.
- 1985 Replica lantern installed
- About ten years later, the aero-beacon was replaced with a VRB-25 lighthouse system.
- 1998 Transferred to the College of the Atlantic as part of the Maine Lights program. It is used as an ecology research station, primarily known for work on finback and humpback whales.
The station is both farther offshore and more exposed than any other lighthouse on the east coast. It sustained serious damage in Hurricane Daisy (1962) and Hurricane Bill (2009). In August 2009, the boathouse was washed away, two walls of the generator building were ripped apart, and all the furniture and equipment on the first floor of the lightkeeper's house were ruined when it flooded almost to the ceiling. The college research station subsequently was closed until August of 2010.
Mount Desert Light was listed on the National Register of Historic Places as Mount Desert Light Station on March 14, 1988, reference number 88000155.
