Scartho (locally /ˈskæθə/) is a suburban village in the southern part of Grimsby, England, and in the unitary authority of North East Lincolnshire. Scartho's population is approximately 11,000. Up until the end of the Second World War it was a village; subsequent post-war expansion on the greenfield areas between Scartho and Grimsby has resulted in the village becoming an outer suburb. Its population has increased through recent urban developments such as Scartho Top.
