Fillingham is a village and civil parish in the West Lindsey district of Lincolnshire, England. It is situated 9 miles (14.5 km) north from the city and county town of Lincoln, and just over 1 mile (1.6 km) west from the A15 road. There is evidence of a Roman camp in the village and Anglo Saxon pottery has also been found. Archaeological excavations have also found evidence of an Anglo Saxon cemetery which may have been associated with a second church in the village. Fillingham Lake is one of the sources of the River Till, a small river whose lower reaches form the Fossdyke Navigation.
