Eurovision Song Contest 2021

The Eurovision Song Contest 2021 was the 65th edition of the Eurovision Song Contest. It consisted of two semi-finals on 18 and 20 May and a final on 22 May 2021, held at Rotterdam Ahoy in Rotterdam, Netherlands, and presented by Chantal Janzen, Edsilia Rombley, Jan Smit, and Nikkie de Jager. It was organised by the European Broadcasting Union (EBU) and host broadcasters Nederlandse Publieke Omroep (NPO), Nederlandse Omroep Stichting (NOS), and AVROTROS, all of which staged the event after AVROTROS had won the 2019 contest for the Netherlands with the song "Arcade" by Duncan Laurence, and following the cancellation of the 2020 contest due to the COVID-19 pandemic.

Broadcasters from thirty-nine countries participated in the contest, of which twenty-six re-entered the artists chosen for 2020 (albeit with different songs, as per the contest's rules). Compared to the 2019 edition, Bulgaria and Ukraine returned while Hungary and Montenegro did not. Armenia and Belarus had originally planned to participate, but the Public Television Company of Armenia (AMPTV) withdrew due to the social and political crises following the Second Nagorno-Karabakh War, and the Belarusian Television and Radio Company (BTRC) was disqualified after submitting entries in violation of the rules twice, and not providing an eligible entry before the deadline.
