Swinton with Warthermarske was historically a township in the ancient parish of Masham in the North Riding of Yorkshire. It became a separate civil parish in 1866. In 1934 the parish was enlarged by the addition of Nutwith and Roomer Common, which had been an area of stinted pasture common to all the townships of the ancient parish of Masham. In 1974 the parish was transferred to the new county of North Yorkshire. The parish now shares a grouped parish council, known as Masham Parish Council, with Masham, Burton on Yore and Ellington High and Low.
