Mie Østergaard Nielsen is a Danish former competitive swimmer who holds the Danish record in several backstroke events.

The 2016 European Aquatics Championships took place from 9 to 22 May 2016 in London, United Kingdom, in the London Aquatics Centre. It was the thirty second edition of the event, and the second held in the same year as a Summer Olympics. Hosts Great Britain headed the medal table for the second successive event; although their swimming return was slightly down, partly down to a small number of star names resting prior to Rio, the gap was made up by an outstanding performance in the diving pool.
