The Lincoln Cliff or Lincoln Edge is a portion of a major escarpment that runs north–south through Lindsey and Kesteven in central Lincolnshire and is a prominent landscape feature in a generally flat portion of the county. Towards its northern end, near Scunthorpe, it is sometimes referred to as the Trent Cliff. The name preserves an obsolete sense of the word "cliff", which could historically refer to a hillside as well as a precipitous rock face.
