The Riverside Archeological District is a historic archaeological site in Gill[2] and Greenfield, Massachusetts.

The Riverside Archeological District encompasses a sizable tract of land north of Turners Falls, a major whitewater rapids on the Connecticut River, north of the eponymous village of Turners Falls, Massachusetts in Gill and Greenfield.

Located in northern Massachusetts near the mouths of four major tributaries to the Connecticut, the area has an archaeological history known to date back to the late Pleistocene.

The area has been recognized has archaeologically significant since the 19th century, with well-attested accounts of small finds and some distinctive burial sites.

The northern boundary is just north of Riverside Cemetery in Gill, and the southernmost portion of the area may extend just across the river into the village of Turners Falls.
