John Du Cameron (Scottish Gaelic: Iain Dubh Camshròn) (executed 23 November 1753) was a Scottish Sergeant in the French Royal Army who came back to Scotland to fight for Prince Charles Edward Stuart during the Jacobite rising of 1745. When the rebellion failed he took to the hills with a band of renegades and fought on until he was captured and hanged in 1753. He is better known by the name of Sergent Mòr (Mòr the Scottish Gaelic for "largeness of size" or "greatness of character").
