Sir George Nayler, KH (bapt. 29 June 1764, Stonehouse, Gloucestershire – 28 October 1831, Hanover Square, Mayfair) was a long-serving officer of arms at the College of Arms in London.
George Nayler was born on 29 June 1764 in Stonehouse, Gloucestershire. He was the fifth son of George Nayler, surgeon, of Stroud, Gloucestershire, and his wife Sarah, daughter of John Fark of Clitheroe, Lancashire.
Originally a miniature painter, Nayler began his heraldic career in 1792 (the year he married Charlotte Williams, the illegitimate daughter of Sir John Guise, 1st Baronet). That year, he acquired a loan of £1300 to purchase the resignation of John Suffield Brown as Genealogist of the Order of the Bath and Blanc Coursier Herald and Nayler was appointed on 15 June 1792. Upon the resignation of Lancaster Herald in 1793, Nayler acquired a post in the College of Arms as Bluemantle Pursuivant for £60 and on the accidental deaths of Somerset and York Heralds at Haymarket in 1794, he was promoted to York Herald that year.
In 1813, Nayler was knighted by The Prince Regent at Carlton House, possibly as a consolation for not having been appointed Garter Principal King of Arms' deputy to invest Alexander I of Russia with the Order of the Garter. In 1816 and 1818 respectively, Nayler was appointed King of Arms of the newly created orders of the Royal Guelphic Order (of which he was made a knight in 1816) and the Order of St Michael and St George.
