The Lochmere Archeological District is a large archeological area on the banks of the Winnipesaukee River in Belknap County, New Hampshire, near the village of Lochmere. The area, part of which is now preserved by the state as the Brennick Lochmere Archaeological Site, is a multi-component site with evidence of human occupation from the Middle Archaic through the Late Woodland periods. The site was occupied in historic times by the Winnipesaukee sub-tribe of the Pennacook people, and is near Aquadoctan (aka The Weirs), one of the largest native towns of prehistoric New Hampshire.
