Kellington is a small village and civil parish in the Selby district of North Yorkshire, England, on the banks of the River Aire. Situated almost equidistant between the towns of Pontefract and Selby, the village dates back to at least the 11th century when it was listed in the Domesday Book (as Chelinctone). The semi-rural community grew in size with the advent of local mining as housing was built to accommodate the workers of nearby Kellingley Colliery.
Due to its location at the southernmost tip of North Yorkshire, the village is close to the borders of West, East and South Yorkshire. Its proximity to both the A19 and M62 major roads has resulted in a steady population growth, although to a lesser extent than its neighbour, Eggborough.
Prior to the nationwide reorganization of municipal boundaries in 1974, Kellington was located in Osgoldcross Rural District in the West Riding of Yorkshire.
