Charles Berkeley, 2nd Viscount Fitzhardinge (14 December 1599 – 12 June 1668) was an English politician who sat in the House of Commons at various times between 1621 and 1668. He supported the Royalist cause in the English Civil War. He succeeded by special remainder to the peerage of his son who predeceased him.
Berkeley was the son of Sir Maurice Berkeley of Bruton, Somerset, of the Bruton branch of the Berkeley family, and his wife Elizabeth Killigrew daughter of Sir Henry Killigrew of Hanworth, Middlesex. He was educated at Eton College in 1613 and matriculated at Queen’s College, Oxford on 3 November 1615 aged 15.
In 1621 Berkeley was elected Member of Parliament (MP) for Somerset. He was knighted in 1623. He was elected MP for Bodmin in 1624 and for Heytesbury in 1625, 1626 and 1628. He sat until 1629 when King Charles decided to rule without parliament for eleven years.
In April 1640, Berkeley was elected MP for Bath in the Short Parliament. He helped to organize the local resistance to ship-money, but was a Royalist during the Civil War executing a Commission of Array in 1642.
Following the Restoration, Berkeley was elected MP for Heytesbury and Bath in 1661 for the Cavalier Parliament. He was involved in a double returns in both seats but was returned at a by-election for Heytesbury after the election had been declared void and sat until his death.
