King's Mill is a former watermill on Bath Row, Stamford, Lincolnshire, England, at the bottom of the sloping road called St Peter's Vale. There is said to have been a mill on this site at the time of the Domesday survey, and took the name 'King's Mill' in the time of King John. The present building dates from the seventeenth century, and is a Grade II listed building. In 1967, it was converted into a day care centre before being refurbished by Burghley Estates in 2018. The building is currently divided between private accommodation and King's Mill Centre, the offices of Bishopsgate Corporate Finance Ltd and BCF Private Equity.
