Heaton Castle (anciently Heton) in the parish of Cornhill-on-Tweed, Northumberland, England, is a ruined historic castle near the Scottish border. It is situated in an elevated position above the south bank of the River Till, 4 miles north-east of Coldstream and 9 miles south-west of Berwick-upon-Tweed, and 2 miles south-east of the River Tweed, the historic border with Scotland.. The castle was slighted in 1496 by King James IV of Scotland, but remnants survive as parts of the walls of outbuildings of a farm now known as Castle Heaton.
