The 2019–20 European windstorm season was the fifth instance of seasonal European windstorm naming in Europe. This is the first season in which the Netherlands meteorological authority took part, joining those of Ireland and the United Kingdom. It comprised a year from 1 September to 31 August, however names were announced six days into that year. The Portuguese, Spanish and French meteorological agencies again collaborated too, joined by the Belgian meteorological agency.
