Machiasport is a town in Washington County, incorporated on January 24, 1826 from part of old Machias.
Indian petroglyphs have been observed at Picture Rocks on Clark's Point. Fort O'Brien guards the entrance to the Machias River at the south end of the main village.
The Larrabee Heath is a coastal raised peatland with appropriate plants such as black crowberry and baked-apple berry. There are a number of game trails which run through this sensitive habitat area managed by the Nature Conservancy.
The town lies primarily on the west side of Machias Bay as the Machias River enters the Bay. It offers many sheltered harbors including the well known Bucks Harbor.
The community is just east of Machias on Maine Route 92.
