The 2021 season of the IFSC Climbing World Cup was the 22nd season of the competition. Bouldering competitions will be held at six stops of the IFSC Climbing World Cup. The bouldering season began on April 16 at the World Cup in Meiringen, and concluded on 26 June with the World Cup in Innsbruck. The International Federation of Sport Climbing had initially scheduled six bouldering events concluding on 24 October, but COVID-19 travel restrictions resulted in the cancellation of events in Wujiang in China and Seoul in South Korea.
At each stop a qualifying was held on the first day of the competition, and the semi-final and final rounds were conducted on the second day of the competition. At the end of the season an overall ranking will be determined based upon points, which athletes were awarded for finishing in the top 30 of each individual event.

The overall ranking is determined based upon points, which athletes are awarded for finishing in the top 30 of each individual event. There are five competitions in the season, but only the best five attempts are counted. The national ranking is the sum of the points of that country's three best male and female athletes. Results displayed (in brackets) are not counted.
