The Royal Order of the Seraphim (Swedish: Kungliga Serafimerorden) (Seraphim being a category of Angels) is a Swedish order of chivalry created by King Frederick I on 23 February 1748, together with the Order of the Sword and the Order of the Polar Star. Since the reorganization of the orders in 1975, the Order of the Seraphim is only awarded to foreign heads of state and members of the royal family (the last non-royal Swedish holder was Sten Rudholm). The order has only one class with the dignity of Knight (Member for women and Member of the Cloth for clergymen), and is the foremost order of Sweden.
