Lead climbing at the 2021 IFSC Climbing World Cup

Competition lead climbing at the 2021 IFSC Climbing World Cup was held at five locations, from 23 June to 4 September 2021. The International Federation of Sport Climbing had initially scheduled six competition-lead climbing events concluding on 17 October, but COVID-19 travel restrictions resulted in the cancellation of the event in Xiamen, China.

The top three in each competition received medals, and at the end of the season, the overall winners were awarded trophies. The overall winners were determined based upon points, which athletes were awarded for finishing in the top 30 of each individual event. Stefano Ghisolfi won the men's seasonal title, Janja Garnbret won the women's seasonal title, and Slovenia won the national team title.
