Spain participated in the Eurovision Song Contest 2011 in Düsseldorf, Germany and selected their entry through a televised national final, organised by the Spanish broadcaster Corporación de Radio y Televisión Española (RTVE). Anne Igartiburu hosted the shows called Destino Eurovisión, broadcast from Sant Cugat del Vallès, Barcelona.

Four televised shows to choose the Spanish entry were broadcast live from TVE's studios in Sant Cugat del Vallès, Barcelona, and were hosted by Anne Igartiburu, with the previous Eurovision entrant Daniel Diges reporting from backstage. The first show was broadcast on 28 January 2011.

24 acts were selected by a panel of experts through casting calls. The 24 candidates were divided into two heats. There they covered past Eurovision Spanish entries and winning songs. At a first stage, the 5-member jury panel (composed of Reyes del Amor, Albert Hammond, Boris Izaguirre, Merche and David Ascanio) had to knock out four acts, thus only 8 were eligible to go through to the semifinal. Five of them qualified from each show for the semifinal - three voted by the audience and another two by the jury.

As a result of this, the semifinal featured 10 acts. They once again performed Eurovision classics. Only three of them won a ticket to the final, one was voted by the audience and another two by the jury.

In the big final of the Spanish selection, the three finalists first performed three different candidate songs each. As a result, the final only featured 9 of the 20 songs selected by the panel from an open submission. After the performances, each jury member awarded 3, 2 and 1 point(s) to the songs by each artist. As a result, each act was left with the song with most points for the final vote. The last decision was taken by the audience, who chose the winning combination that became the Spanish representative in Eurovision 2011.Lucía Pérez won the final with 68% of the total vote".
