The 2017–2018 European windstorm season was the third instance of seasonal European windstorm naming. France, Spain and Portugal took part in winter storm naming for the first time this season.
The season started on 12 September 2017 with the formation of Storm Aileen. It was subsequently marked by many high-impact storms which caused severe loss of life and widespread damage, including Ophelia, Eleanor, David and Emma. The season concluded on 17 June 2018 with the dissipation of off-season Storm Hector.
