The Eurovision Song Contest 2021 is set to be the 65th edition of the Eurovision Song Contest. The contest will be held in Rotterdam, the Netherlands, following the country's victory at the 2019 contest with the song "Arcade" by Duncan Laurence. The Netherlands was due to host the 2020 contest, before it was cancelled due to the COVID-19 pandemic. It will be the fifth time that the Netherlands hosts the contest, the last time having been the 1980 contest.
Organised by the European Broadcasting Union (EBU) and host broadcasters Nederlandse Publieke Omroep (NPO), Nederlandse Omroep Stichting (NOS) and AVROTROS, the contest will be held at Rotterdam Ahoy and will consist of two semi-finals on 18 and 20 May, and the final on 22 May 2021. The EBU discussed carryovers between the 2020 and 2021 contests, and several participating countries allocated the same artists who were due to represent them in 2020.
Forty-one countries will participate in the contest; the exact same line-up of countries that would have competed in 2020. Bulgaria and Ukraine will return after their absences from the 2019 contest, while Hungary and Montenegro confirmed their non-participation.
