Worksop (previously Blyth and Cuckney) was a Rural District in Nottinghamshire, England. It originated as Worksop Rural Sanitary District in 1872. In 1894, under the Local Government Act 1894, the Worksop RSD was split to match county borders, with the West Riding of Yorkshire part becoming the Kiveton Park Rural District, and the Derbyshire part becoming Clowne Rural District. The remainder, in Nottinghamshire, became the Blyth and Cuckney Rural District, taking its name from two of the parishes, Blyth and Cuckney. In 1925 it was renamed Worksop Rural District.
