The FIS Ski Jumping World Cup has been contested since the 1979–80 season.

Competitors are awarded a fixed number of points in each event according to their ranking, and the overall winner is the one with most accumulated points. FIS Ski Flying World Cup is contested as a sub-event of the World Cup, and competitors collect only the points scored at ski flying hills from the calendar. The ski jumping at the FIS Nordic World Ski Championships was first contested in 1925. The team event was introduced in 1982, while the women's event was first held in 2009. The FIS Ski Flying World Championships was first contested in 1972 in Planica. The Four Hills Tournament has been contested since the 1952–53 season. It is contested around the New Year's Day at four venues – two in Germany (Oberstdorf and Garmisch-Partenkirchen) and two in Austria (Innsbruck and Bischofshofen), which are also scored for the World Cup. Those events are traditionally held in a slightly different format than other World Cup events (first round is held as a knockout event between 25 pairs of jumpers), and the overall winner is determined by adding up individual scores from every jump.
