Blyth is a village in the county of Nottinghamshire, in the Midlands of England, north west of East Retford, on the River Ryton.

The priory church of St. Mary and St. Martin is one of the oldest examples of Norman architecture in the country. It was part of a Benedictine monastery founded in 1088. Blythe Hall was built at the eastern end of the church and was demolished in 1972.

There is a stone building with a seven hundred year old doorway, said to have been built by the Knights Hospitaller of St. John of Jerusalem.
