Deanston (Scottish Gaelic: Baile an Deadhain) is a village in the Stirling council area, Scotland, on the south bank of the River Teith east of Doune, in south-west Perthshire.

At its peak, the mill had over 1000 workers and had the largest waterwheel in Europe, Hercules, with a diameter of 36 feet 6 inches (11.13 metres).

This unusual arrangement probably reflects the nature of the site, a narrow flat terrace facing the River Teith with the land rising steeply behind.

Despite their early date, the houses are only listed as [Scottish] Category C. The Mill buildings (B) were commenced in 1785, but saw significant changes over the years, including a serious fire in 1796.

Perhaps the most extraordinary feature of the village is the 1.5 kilometre long mill lade (E - only part shown on plan), built circa 1826.

This replaced an earlier shorter mill lade and was built to channel the waters of the River Teith to power a series of five large waterwheels.

This was apparently as a direct result of a mission by Richard Arkwright, the towering figure of the early Industrial Revolution, to set up cotton spinning factories in Scotland according to his principles.
