Finedon is a town and civil parish in North Northamptonshire, England, with a population at the 2021 census of 4,552. In 1086 when the Domesday Book was completed, Finedon was a large royal manor, previously held by Queen Edith, wife of Edward the Confessor. From the 1860s the parish was much excavated for its iron ore, which lay underneath a layer of limestone and was quarried over the course of 100 years or more.
