Storm Abigail was an extratropical cyclone that brought high winds, rain, lightning, and snow across northern Scotland. The first named storm, it is the first ever storm to be officially named by the Met Office of the United Kingdom and Met Éireann of the Republic of Ireland, on 10 November 2015.

Weather system naming in Europe follows several multinational schemes under the EUMETNET framework. On the north Atlantic coast, the United Kingdom's Met Office, in collaboration with its Irish counterpart Met Éireann and, since 2019, its Dutch counterpart the Royal Netherlands Meteorological Institute (KNMI), decided to introduce a storm naming system following the St Jude's day storm on 27–28 October 2013 which caused 17 deaths in Europe and the 2013–14 Atlantic winter storms in Europe to give a single, authoritative naming system to prevent confusion with the media and public using different names for the same storms. The first European windstorm to be named was Abigail on 10 November 2015. The definitive list is combined from suggestions from the three countries.
