The 2018 World Para Swimming European Championships, known for sponsorship reasons as the 2018 World Para Swimming Allianz European Championships took place in Dublin, Ireland from 13 to 19 August 2018. It was the 5th edition of the Championships, the first under the new World Para Swimming branding, and the first time Ireland had hosted.[1] Ukraine topped the medal table for the fourth time in a row.[2]
Formerly the IPC Swimming European Championships, this was the first edition of the championships since IPC undertook a rebrand of all sports for which they are the governing body, including the 'World Para' title for the committees running each sport. IPC Swimming was rebranded World Para Swimming in 2016; its first World Para Swimming Championships were held in 2017, and the European Championships followed suit in 2018.
