Mid Gleniron is a prehistoric site in Dumfries and Galloway used in the Neolithic and Bronze Age. The site is a scheduled ancient monument that comprises a group of six burial cairns. Two of the cairns, Mid Gleniron I and Mid Gleniron II are chambered cairns of the Clyde tradition. These are of historic importance because of their multi-stage construction which provides evidence for the development of Clyde cairns at the beginning of the Neolithic period.
