Cauldron Linn, or Caldron Linn, is a waterfall on the River Devon on the border between Clackmannanshire and Perth and Kinross in Scotland.
Caldron Linn is about a mile below Rumbling Bridge, and can be accessed through fields by Powmill, with a 150 ft slippery descent to reach it. The height of its fall was lessened in 1886 by rock fall.
The Scottish Tourist, an 1838 guidebook, says of the waterfall:
The water flow of the Linn is now diminished by a recent hydro-electric scheme commissioned in 1993.
The Linn was famously visited by Robert Burns in 1787 in the company of his friends Gavin Hamilton and Crauford Tait of Harvireston.
