Marshall Point Light Station is a lighthouse at the entrance of Port Clyde Harbor in Port Clyde, Maine. The light station was established in 1832. Established in 1832 to assist boats entering and leaving Port Clyde Harbor. The original lighthouse was a 20-foot (6.1 m) tower lit by seven lard oil lamps with 14-inch reflectors.
The original tower was replaced with the present lighthouse in 1857. The lighthouse is a 31-foot (9.4 m) tall white brick tower on a granite foundation. The tower was originally lit with a 5th order Fresnel lens. A raised wooden walkway connects the tower to land.
The lighthouse was automated in 1980 and the original Fresnel lens was replaced with a modern 12 inches (300 mm) optic. The original lens is at the Maine Lighthouse Museum in Rockland. In 1986, the St. George Historical Society restored the keeper's house and established the Marshall Point Lighthouse Museum there, presenting the histories of Marshall Point Light and other nearby lighthouses. The light station was added to the National Register of Historic Places in 1988.
The lighthouse appeared in the 1994 film Forrest Gump. The light station was transferred to the town of St. George in 1998 under the Maine Lights Program. The fog signal has been dismantled but the bell remains on display.
