Chirnside is a hillside village in Berwickshire in Scotland, 9 miles (14 km) west of Berwick-upon-Tweed and 7 miles (11 km) east of Duns.
David Hume, the Scottish Enlightenment philosopher, lived in Ninewells House, just south of the village
Chirnside is also the final resting place of Jim Clark, former world champion Formula One racing-car driver. Close to the churchyard in which Clark is buried, there is a memorial plaque and clock at the side of the main road through the village. The Jim Clark Motorsport Museum can be found in Duns.
