John Ward, 2nd Viscount Dudley and Ward (22 February 1725 – 10 October 1788) was a British peer and politician.
Ward was the son of John Ward, 1st Viscount Dudley and Ward, and his first wife Anna Maria (née Bourchier). He was returned to Parliament as one of two representatives for Marlborough in 1754, a seat he held until 1761, and then represented Worcestershire until 1774. The latter year he succeeded his father in the viscountcy and entered the House of Lords. Ward married Mary, daughter of Gamaliel Fair, gardener and seeds-man, died December 17, 1758, aged 69. Ward died in October 1788, aged 63. As he had no sons he was succeeded in the viscountcy by his half-brother William.
He had a natural daughter Anna Maria Ward (1778–1837), by his Viscountess (when she was still Mrs. Mary Baker, whom he later married). Lord Dudley in his will made an ample provision for the girl and appointed his widow Lady Viscountess Ward (d. 1810) and Henry Jerome de Salis as her guardians. She married Sir Horace St Paul, 1st Baronet, MP, on 14 May 1803.
