Ravens' Crag Linn is a waterfall located on a small stream approximately one kilometre west of Allensford in County Durham, England, where the water tumbles over a steep cliff into the surrounding woodland.

It sits near the River Derwent and can be reached via a spur path branching off the footpath that leads to the better-known Wharnley Burn Waterfall. Access is considered difficult, requiring visitors to push through thick woodland.

A steep drop at the falls themselves makes the approach genuinely hazardous, and anyone venturing there is urged to proceed with great caution.
