Sir Philip Perceval (1605 – 10 November 1647) was an English politician. He was knighted in 1638, obtained grants of forfeited lands in Ireland to the amount of 101,000 acres (41,000 ha), and lost extensive property in Ireland owing to the rebellion of 1641. He opposed Charles I's intention of granting the demands of the Irish Confederates in order to employ them in England: joined the parliamentary party in 1644, obtaining a seat in the House of Commons of England as member for Newport, Cornwall, where he threw in his lot with the moderate presbyterians; compelled to retire into the country owing to his opposition to the independents, September 1647.
Philip was the younger of the two sons of Richard Perceval of Tickenham, Somerset, by his second wife Alice, daughter of John Sherman of Ottery St. Mary, Devon. Philip's elder brother Walter and himself had been appointed by their father joint successors in his office of registrar of the Irish court of wards. Walter died in 1624, so that Philip obtained the family estates in England and Ireland, and the sole enjoyment of the Irish registrarship.
Perceval now definitely settled in Ireland, and by means of his interest at court gradually obtained a large number of additional offices. In 1625 he was made keeper of the records in Birmingham Tower. In 1628 he was joined with Henry Andrews in the offices of clerk of the crown to the Court of King's Bench (Ireland) and the Court of Common Pleas (Ireland), and keeper of the rolls of those tribunals; and in 1629 he was made joint collector of customs at Dublin with Sir Edward Bagshawe of Finglas. By early 1634 his friends in Dublin included Sir Philip Mainwaring and Sir George Radcliffe who were two of Wentworth's closest advisers. In 1636 Perceval was admitted to King's Inns, Dublin, and on 2 June the same year he was knighted by Lord Deputy of Ireland. Thomas Wentworth. In 1638 he, with Sir James Ware, obtained the monopoly of granting licenses for the sale of ale and brandy, and was also made a member of the privy council.
