The South Esk (Scottish Gaelic: Easg Dheas) is a river in Angus, Scotland. It rises in the Grampian Mountains at Loch Esk in Glen Doll and flows through Glen Clova to Strathmore at Cortachy, 5 km north of Kirriemuir. Its course takes it past Brechin and enters the North Sea at Montrose.^[1]

The river gives its name to the title of Earl of Southesk, held by the Carnegie family.^[2]
