Part of the 2024–25 European windstorm season

Storm Éowyn (/ˈwɪn/ AY-oh-win) was a powerful and record-breaking extratropical cyclone which hit Ireland, the Isle of Man and the United Kingdom on 24 January 2025 and hit Norway on the night of 24 January into 25 January 2025. The twenty-seventh storm of the 2024–25 European windstorm season (and the fifth to be named by the western naming group comprising the United Kingdom, Ireland and the Netherlands), Éowyn was named by the UK Met Office on 21 January 2025.

Widespread red weather warnings were issued across Ireland, Scotland and the Isle of Man, whilst amber and yellow warnings were issued around Wales, England and Norway ahead of the rapidly strengthening storm. It was the most powerful and severe to hit Ireland since Hurricane Debbie in 1961, with wind records breaking an 80-year-old record for the country.
