Foulden is a civil parish and village in the Berwickshire area of Scottish Borders, Scotland, situated not far above the Whiteadder Water, and 7 miles (11 km) west of Berwick-upon-Tweed.

Originally one of the superiorities of Coldingham Priory (a part of the parish is still called Nunlands), at a very early date it was resigned to the Ramsay family for whom it was erected into a Free Barony.

William de Ramsay swore fealty to King Edward I of England, for his lands of Dalwolsie (Dalhousie), Edinburghshire, and of Foulden, Berwickshire, in 1296, and again in 1304.

The local manor, Foulden House, rebuilt by the Wilkies circa 1800, had a main Georgian block of three and a half stories, flanked by peristyled and porticoed two-storey pavilion wings.

Together the three areas form Foulden, Mordington and Lamberton Community Council, which is run by locally elected non party political volunteers.
