The International Skating Union (ISU) is the international governing body for competitive ice skating disciplines, including figure skating, synchronized skating, speed skating, and short track speed skating. It was founded in Scheveningen, Netherlands, in July 1892, making it one of the oldest international sport federations. The ISU was formed to establish standardized international rules and regulations for the skating disciplines it governs, and to organize international competitions in these disciplines. It is now based in Switzerland.

Ice skating is the self-propulsion and gliding of a person across an ice surface, using metal-bladed ice skates. People skate for various reasons, including recreation (fun), exercise, competitive sports, and commuting. Ice skating may be performed on naturally frozen bodies of water, such as ponds, lakes, canals, and rivers, and on human-made ice surfaces both indoors and outdoors.
