The Eurovision Song Contest 2020 was planned to be the 65th edition of the Eurovision Song Contest. It would have taken place in Rotterdam, Netherlands, following the country's victory at the 2019 contest with the song "Arcade" by Duncan Laurence. This edition was the first and only one in the contest's history to be cancelled, with it being called off on 18 March 2020 due to the COVID-19 pandemic.

The Eurovision Song Contest, often known simply as Eurovision, is an international song competition organised annually by the European Broadcasting Union. Each participating country submits an original song to be performed live and transmitted to national broadcasters via the Eurovision and Euroradio networks, with competing countries then casting votes for the other countries' songs to determine a winner.
