Scrivelsby is a village and ecclesiastical parish in the East Lindsey district of the County of Lincolnshire, England. It is situated 2 miles (3.2 km) south of Horncastle and is on the B1183 road 1 mile (1.6 km) east from the A153 road. It is administered by the civil parish of Mareham on the Hill. Historically the manor was held by grand serjeanty, a form of feudal tenure which required the performance of a ceremonial service rather than a money payment – in this case as the King's Champion.
