The Danube Arena[1] (in Hungarian: Duna Aréna, unofficially Dagály Budapest Aquatics Complex) is an aquatics complex located in Budapest, Hungary.

It was designed by Marcell Ferenc and built between 2015 and 2017.

Originally, the arena was intended to be the home of the World Aquatics Championships in 2021, but after the original host venue for the 2017 Championships in Guadalajara withdrew in February 2015, Budapest, including the Danube Arena, was announced as the host for the 2017 Championships instead.

[2] Following the decision to move Budapest's hosting duties four years earlier, the building was re-designed, partially due to the originally-planned building being too small to be a potential venue for the 2024 Summer Olympics and also because of the advanced deadline.
