Rutter Force is a 30-foot (9.1 m) high horseshoe-shaped waterfall in the English county of Cumbria. Rutter Mill, a former watermill, and Rutter Mill Ford are adjacent to the falls. The falls lie on the Hoff Beck, which forms the boundary between the civil parishes of Hoff and Ormside and is a tributary of the River Eden. Although not actually in Yorkshire, the falls are in the far north-west corner of the designated area of the Yorkshire Dales National Park.
