World Climbing Series

World Climbing Series is a competition climbing event series held during the year at various locations around the world, organized by World Climbing. At each event, the athletes compete in three disciplines: lead, bouldering, and speed. The number of events varies from year to year, and the winners for each discipline are decided by the points accumulated in the year.

Previously called the IFSC World Cup, the first season was held in 1989 and included only lead competition climbing events. Speed climbing was introduced in 1998, and bouldering in 1999. For 18 seasons, from 1989 to 2006, World Cups were held under the auspices of the International Council for Competition Climbing which was part of the UIAA; they were called UIAA Climbing World Cups. Since 2007, they have been held under the auspices of World Climbing, known as the International Federation of Sport Climbing (IFSC) until 2025.

The competition was renamed from IFSC World Cup to World Climbing Series in December 2025, as part of IFSC's rebranding to World Climbing.
