The Royal Norwegian Yacht Club (Norwegian: Kongelig Norsk Seilforening, KNS) is a yacht club in Oslo, Norway. The club was founded in 1883 as country-wide organisation with affiliated local yacht clubs. In 1884, it was granted the right for members to fly the naval Ensign of Norway with the Royal cypher on a centrally placed white field. In 1970, it was reorganized as local club for the Oslo area, under a new nationwide federation of yacht clubs (Norges Seilforbund). To date, the club has some 4,000 members.
The club premises are at Bygdøy in Frognerkilen, where the clubhouse is named "Dronningen" ('The Queen').[1]
The Royal Norwegian Yacht Club traditionally arranges the big Norwegian regatta called "Færderseilasen" every year, on the second weekend in June.
