swimming events were included at the inaugural 2015 European Games took place at the Baku Aquatics Centre, Baku 42 events were contested in long course conditions. Swimming was not included in the earliest list of sports confirmed for the 2015 Games, as the European swimming authorities at that stage were minded not to take part. However, following negotiations with the organising authorities, a compromise was reached whereby, in 2015, these events were for junior swimmers only - in effect, under 18 for men, under 16 for women.
In effect, therefore, the swimming portion of the 2015 European Games doubled as the 2015 European Junior Swimming Championships. Swimming events did not return for the 2019 Games in Minsk.
A number of non-Olympic distances have been raced, in addition to a full Olympic programme. The 50 metre sprint in backstroke, breaststroke, and butterfly will be held for both genders, the 800 metre freestyle for men, the 1500 metre freestyle for women and mixed gender 4 x 100 metre relays, both freestyle and medley.
