John Hamilton-Leslie, 9th Earl of Rothes

John Hamilton-Leslie, 9th Earl of Rothes (1679–1722), was a Scottish nobleman who fought on the side of George I during the Jacobite rising of 1715.

John Hamilton-Leslie, born in 1679, was the eldest son of Charles Hamilton, 5th Earl of Haddington, and Margaret Leslie, 8th Countess of Rothes.

In the Jacobite rising of 1715, Hamilton-Leslie fought for George I in Scotland against the pretender James Francis Edward Stuart.

In a skirmish at Kinross, Hamilton-Leslie led a troop of the Scots Greys that defeated the Jacobites and took Sir Thomas Bruce captive.

In 1716, after the defeat of the Jacobites, George I appointed Hamilton-Leslie as governor of Stirling Castle to compensate him for his property losses during the insurgency.
