Spain participated in the Eurovision Song Contest 2015 with the song "Amanecer", written by Tony Sánchez-Ohlsson, Peter Boström and Thomas G:son. The song was performed by Edurne, who was selected by Spanish broadcaster Televisión Española (TVE) in January 2015 to represent the nation at the 2015 contest in Vienna, Austria. "Amanecer" was later presented to the public in March 2015. As a member of the "Big 5" (France, Germany, Italy, Spain and the United Kingdom), Spain competed directly in the final on 23 May 2015 and did not have to qualify from one of two semi-finals held on 19 May and 21 May. However, Spain was obligated to vote in the first semi-final. In Spain's fifty-fifth Eurovision appearance on 23 May, "Amanecer" finished in twenty-first place out of 27 competing songs.

Prior to the 2015 contest, Spain had participated in the Eurovision Song Contest fifty-four times since its first entry in 1961. 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 2014, Spain placed tenth with the song "Dancing in the Rain" performed by Ruth Lorenzo.
