2021 FIG Rhythmic Gymnastics World Cup series

The 2021 FIG World Cup circuit in Rhythmic Gymnastics is a series of competitions officially organized and promoted by the International Gymnastics Federation. The events had originally been scheduled to be held in 2020, but were postponed to 2021 due to the COVID-19 pandemic.

With stopovers in Europe and Asia, the World Cup competitions are scheduled for March 26–28 in Sofia (BUL), April 16–18 in Tashkent (UZB), May 7–9 in Baku (AZE), May 28–30 in Pesaro (ITA). World Challenge Cup competitions are scheduled for July 2–4 in Minsk (BLR), July 9–11 in Moscow (RUS), October 15–17 in Cluj Napoca (ROU). Originally, the Cluj Napoca stage was scheduled to be held June, but it was postponed to October, and the World Challenge Cup stage in Portimão, Portugal, was eventually cancelled.

This year's World Cup series also served as qualifications for the 2020 Summer Olympics, with the top 3 ranked gymnasts (max. 1 per NOC), not already qualified at the 2019 Rhythmic Gymnastics World Championships, achieving a quota for their NOC at the individual all-around event.
