Torrance Linn is a waterfall on the Rotten Calder Water, situated within Calderglen Country Park east of East Kilbride in South Lanarkshire, Scotland.

It is also known locally as Fairy Linn or Walk Fort Linn, and sits among a series of notable falls along this stretch of river that includes Black Linn, Trough Linn, and Calderwood Linn.

The Rotten Calder gorge through Calderglen was historically celebrated for its romantic grandeur, lush ivy-clad crags, and traces of 18th- and 19th-century landscape features.

Torrance Linn is an early highlight on the popular out-and-back walk through the park, which follows the river downstream past several further waterfalls to the site of Calderwood Castle.
