The European Junior Swimming Championships (50 m) is an annual swimming competition for European swimmers organized by the Ligue Européenne de Natation and held over five days.

[2] Until 1989 the European Junior Diving Championships was held together with European Junior Swimming Championships, and even since then has sometimes been co-hosted with the European Junior Swimming Championships, for example in Palma de Mallorca in 2006.

A stand-alone European Junior Swimming Championships was not held in 2015; instead the junior swimming events formed the bulk aquatics program at the 2015 European Games.

European Games champions and medalists for that year were simultaneously treated as champions and medalists of the European Junior Swimming Championships for the purposes of 2015.

[56] All records were set in finals unless noted otherwise.
