John Hervey (18 August 1616 – 18 January 1680) was an English courtier and politician who sat in the House of Commons from 1661 to 1679. He fought for the Royalist cause in the English Civil War. Hervey was the eldest son of Sir William Hervey of Ickworth and his first wife Susan Jermyn, daughter of Sir Robert Jermyn of Rushbrooke. He travelled abroad in 1636 and was at Leyden in 1637. From about 1641 to 1646 he was a gentleman of the privy chamber. He was a captain of horse in the Royalist army from 1642 to 1646. In 1646, he compounded on goods and chattels valued at £240, and was fined £24 on the Exeter articles. He succeeded to Ickworth on the death of his father in 1660.
