Richard Herbert, 2nd Baron Herbert of Chirbury (c. 1604 – 13 May 1655) was an Anglo-Welsh Member of Parliament, a Royalist who fought with the rank of Colonel in the English Civil War, and a peer whose membership of the House of Lords was curtailed by its abolition in 1649.
Herbert, born about 1604, was the elder son of the poet Edward Herbert, 1st Baron Herbert of Cherbury, of Montgomery Castle, and of Mary, the daughter and heiress of Sir William Herbert (d. 1593), both members of a collateral branch of the family of the Earls of Pembroke. He was born while his father was under the age of twenty-one.
On 19 November 1627 at Bridgwater House, Barbican, City of London, Herbert married Lady Mary Egerton (c. 1604–1659), one of the five daughters of John Egerton, 1st Earl of Bridgwater. Their children were two sons, Edward and Henry, and two daughters, Frances and Florence.
As the result of his marriage, Herbert was the brother-in-law of David Cecil, 3rd Earl of Exeter (c. 1600–1643), Sir John Hobart (1593–1647), Richard Vaughan, 2nd Earl of Carbery (c. 1600–1686), Oliver St John, 5th Baron St John of Bletso (d. 1642), and John Egerton, 2nd Earl of Bridgewater (1623–1686).
A Royalist, in March 1640 Herbert was elected to the Commons in the Short Parliament representing Montgomeryshire. In October of the same year, at the outset of the Long Parliament, he was elected from Montgomery. He was appointed Royal Governor of Bridgnorth in 1642, as the English Civil War was breaking out. At his own expense, in the king's cause he raised both a foot regiment and a troop of horse, and the king gave him the rank of Colonel. On 12 October 1642 he was disabled from sitting in parliament, on account of having executed the Commission of Array in Shropshire and of joining the king at Oxford. In 1643, he graduated Master of Arts of the University of Oxford and became Governor of Ludlow.
