The 2020–2021 European windstorm season was the sixth instance of seasonal European windstorm naming in Europe. This is the second season in which the Netherlands participates, joining Ireland's and the United Kingdom's meteorological agencies. The new season's storm names were released on 1 September 2020. Storms that occur up until 31 August 2021 will be included in this season. The Portuguese, Spanish, and French meteorological agencies will again collaborate too, joined by the Belgian meteorological agency.
