Birch Point, also known as Clark's Point, is a peninsula in Machiasport, Maine. It separates Sanborn Cove to the north from Larrabee Cove to the south on the west side of Machias Bay, a short way south of the mouth of the Machias River. The point is of prehistoric and historic importance to the local Passamaquoddy people, as it is the site of large panels of rock art which have been listed on the National Register of Historic Places.
