Spain in the Eurovision Song Contest 2021

Prior to the 2021 contest, Spain had participated in the Eurovision Song Contest fifty-nine times since its first entry in 1961.[2] The nation has won the contest on two occasions: in 1968 with the song "La, la, la" performed by Massiel and in 1969 with the song "Vivo cantando" performed by Salomé, the latter having won in a four-way tie with France, the Netherlands and the United Kingdom. Spain has also finished second four times, with Karina in 1971, Mocedades in 1973, Betty Missiego in 1979 and Anabel Conde in 1995. In 2019, Spain placed twenty-second out of twenty-six countries with the song "La venda" performed by Miki.

The Spanish national broadcaster, Televisión Española (TVE), broadcasts the event within Spain and organises the selection process for the nation's entry. The Spanish broadcaster had used both national finals and internal selection to choose the Spanish entry in the past. For 2018 and 2019, TVE used the reality television singing competition Operación Triunfo (the Spanish version of Star Academy) to select the artist and song to represent Spain in the contest, as they had previously done from 2002 to 2004.

The Eurovision Song Contest 2021 is scheduled to take place at Rotterdam Ahoy in Rotterdam, the Netherlands, and will consist of two semi-finals held on 18 and 20 May, and the grand final on 22 May 2021.[6] As Spain is a member of the Big 5, their entry for 2021 will directly qualify to the final, along with France, Germany, Italy, the United Kingdom, and host country the Netherlands.[7] The top ten countries from each semi-final progress to the grand final.
