St. Mary's Priory, North Berwick, was a monastery of nuns in medieval East Lothian, Scotland. Founded by Donnchad I, Earl of Fife around 1150, the priory lasted for more than four centuries, declining and disappearing after the Scottish Reformation. It had been endowed by the Earls of Carrick as well as the Earls of Fife, but over time lost its dependence on these and came to be controlled by the more locally based Home family, who eventually acquired the priory's lands as a free barony.

North Berwick is a seaside town and former royal burgh in East Lothian, Scotland. It is situated on the south shore of the Firth of Forth, approximately 20 miles (32 km) east-northeast of Edinburgh. North Berwick became a fashionable holiday resort in the nineteenth century because of its two sandy bays, the East Bay and the West Bay, and continues to attract holidaymakers. Golf courses at the ends of each bay are open to visitors.
