Viscount Brentford, of Newick in the County of Sussex, is a title in the Peerage of the United Kingdom. It was created in 1929 for the Conservative politician Sir William Joynson-Hicks, 1st Baronet, chiefly remembered for his tenure as Home Secretary from 1924 to 1929. He had already been created a baronet, of Holmsbury, in the Baronetage of the United Kingdom, on 20 September 1919. His younger son, the third Viscount, was also a Conservative politician. On 29 January 1956, two years before he succeeded his elder brother in the viscountcy, he was created a baronet, of Newick. As of 2017[update] the titles are held by the third Viscount's son, the fourth Viscount, who succeeded in 1983, a retired solicitor and has served as the president of the Church Society.
