Artle Beck is a minor river of Lancashire, England. Rising at the confluence of Udale Beck and Foxdale Beck below Fosdale Bridge and Udale Bridge near Crossgill, Artle Beck flows northwest through steep-sided woodland, passing beneath Raven Scar on its way to Gresgarth Hall. From there, the beck continues north, skirting around the village of Caton before meeting the River Lune opposite Halton Park. The beck is dammed at Gresgarth Hall and feeds a mill leat which runs separately through Caton. Two of the (originally three) mills are still standing but have been converted for other uses. The leat empties separately into the Lune at Low Mill about half a mile downstream from the mouth of Artle Beck itself.
