The Loch Ness Supergroup is one of the subdivisions of the Neoproterozoic sequence of sedimentary rocks (or their metamorphic equivalents) in the Scottish Highlands.[1] It is found everywhere in tectonic contact above the older Wester Ross Supergroup. It is thought to be unconformable overlain by the Cryogenian to Cambrian Dalradian Supergroup.[2]
