The Big Black Site is an archaeological site in remote northwestern Aroostook County, Maine. The 1-acre (0.40 ha) site, located near the mouth of the Big Black River exhibits evidence of occupation and use over a period of several thousand years, ending in historic times. The site is significant as a well-preserved site (although slightly damaged by the presence of a 20th-century sporting camp over part of it) on an undammed river, and was, at the time of its listing on the National Register of Historic Places in 1975, expected to yield significant information about the area's prehistory.
