Portugal was represented at the Eurovision Song Contest 2003 with the song "Deixa-me sonhar (só mais uma vez)" written by Paulo Martins and performed by Rita Guerra. The Portuguese participating broadcaster, Radiotelevisão Portuguesa (RTP), organised the national final Canção para Eurovisão 2003 in order to select its entry, after having previously selected the performer internally. RTP returned to the Eurovision Song Contest after a one-year absence following their withdrawal in 2002 as one of the bottom six countries in the 2001 contest. The winning song of the national final was selected exclusively by public televoting. "Deixa-me sonhar (só mais uma vez)" emerged as the winning song with 75% of the votes.
The song competed in the Eurovision Song Contest which took place on 24 May 2003. Performed during the show in position 7, it placed twenty-second out of the 26 participating songs from different countries, scoring 13 points.
