The Most Noble Order of the Garter is an order of chivalry founded by King Edward III of England in 1348. It is the most senior order of knighthood in the British honours system, outranked in precedence only by the Victoria Cross and the George Cross. The Order of the Garter is dedicated to the image and arms of Saint George, England's patron saint.

Appointments are made at the Sovereign's sole discretion. Membership of the Order is limited to the Sovereign, the Prince of Wales, and no more than 24 living members, or Companions. The order also includes supernumerary knights and ladies (e.g., members of the British royal family and foreign monarchs). New appointments to the Order of the Garter are often announced on St George's Day (23 April), as Saint George is the order's patron saint.

The order's emblem is a garter with the motto Honi soit qui mal y pense (Middle French: "Shame on him who thinks evil of it") in gold lettering. Members of the order wear it on ceremonial occasions.

King Edward III founded the Order of the Garter around the time of his claim to the French throne.[1] The traditional year of foundation is usually given as 1348 (when it was formally proclaimed). However, the Complete Peerage, under "The Founders of the Order of the Garter", states the order was first instituted on 23 April 1344, listing each founding member as knighted in 1344. The list includes Sir Sanchet D'Abrichecourt, who died on 20 October 1345. Other dates from 1344 to 1351 have also been proposed. The King's wardrobe account shows Garter habits first issued in the autumn of 1348. Also, its original statutes required that each member of the Order already be a knight (what would now be referred to as a knight bachelor) and some of the initial members listed were only knighted that year. The foundation is likely to have been inspired by the Spanish Order of the Band, established in about 1330.

The earliest written mention of the Order is found in Tirant lo Blanch, a chivalric romance written in Catalan mainly by Valencian Joanot Martorell. It was first published in 1490. This book devotes a chapter to the description of the origin of the Order of the Garter.
