The Royal Norwegian Order of St. Olav (Norwegian: Den Kongelige Norske St. Olavs Orden; or Sanct Olafs Orden, the old Norwegian name) is a Norwegian order of chivalry that was instituted by King Oscar I of Norway and Sweden on August 21, 1847, as a distinctly Norwegian order. It is named after King Olav II, known to posterity as St. Olav. Nobility was abolished in Norway in 1821.
