John Dunn-Gardner, of Soham Mere and of Chatteris House, Isle of Ely, in Cambridgeshire, was a British politician and landowner. From his birth until his de-legitimization in 1843, he was the eldest legal son and heir apparent of George Townshend, 3rd Marquess Townshend (1778-1855), who was not, however, his biological father. He is otherwise notable in relation to the tangled marital history of his mother, the Marchioness Townshend.
