The FIS Alpine World Ski Championships 2021 were held from 8 to 21 February in Cortina d'Ampezzo, Italy.

[1] In May 2020, the Italian Winter Sports Federation (FISI) and the event organizing committee asked the International Ski Federation (FIS) to postpone the event until 2022 due to the COVID-19 pandemic,[2] however, the request was rejected by FIS, and the organizers then moved forward with plans for 2021.

This was the seventh edition in Italy; in addition to Cortina, other sites were Bormio (2005, 1985), Sestriere (1997), and Val Gardena (1970).

Sestriere was also the alpine host for the 2006 Winter Olympics, with women's speed events at San Sicario.

On 9 December 2019, the World Anti-Doping Agency (WADA) banned Russia from all international sport for a period of four years, after the Russian government was found to have tampered with laboratory data that it provided to WADA in January 2019 as a condition of the Russian Anti-Doping Agency being reinstated.
