The Cochno Stone is a large Cup and ring marked rock at Auchnacraig, Faifley, West Dunbartonshire, Scotland. The Bronze Age stone measuring 42 feet (13 m) by 26 feet (7.9 m) was rediscovered in 1887 by the Rev. James Harvey. It features around 90 carved indentations, considered to be one of the finest sets of petroglyphs in Scotland. The stone was reburied in the 1960s to protect it against vandalism. In 2015 it was partially re-exposed for investigation during a 3-day dig by a team involving archaeologists from the University of Glasgow, with a more complete re-exposure following a year later.
