Penny Spot Beck is a minor watercourse that is entirely in the County of Norfolk. This small short Beck rises in within the Parish of Dereham ½ mile south of the village of Swanton Morley (grid reference TG018150). The Beck is a tributary of the River Wensum. The Headwater is a small pool in a field 50 feet (15 m) south west of the intersection of Tuddenham and Norwich Roads, from here the Beck flows east and then north east across open farmland where various streams and ditches contribute to its flow.
