Cotter Force is a small stepped waterfall on Cotterdale Beck, a minor tributary of the River Ure, located near the mouth of Cotterdale — a side dale of Wensleydale in North Yorkshire.

The falls drop a total of 33 feet (10 m) across six individual steps, with the largest single drop around 5 feet. The force narrows toward the top and widens at the base, and sits tucked within secluded woodland.

Despite its hidden setting, Cotter Force is one of the most accessible waterfalls in the Yorkshire Dales.

A short path of roughly 500 metres leads from a roadside lay-by on the A684 west of Hawes, and the graded surface is suitable for pushchairs and wheelchair users.
