Portugal in the Eurovision Song Contest 2009

Portugal was represented at the Eurovision Song Contest 2009 with the song "Todas as ruas do amor", written by Pedro Marques and Paulo Pereira, and performed by the group Flor-de-Lis. The Portuguese participating broadcaster, Rádio e Televisão de Portugal (RTP), organised the national final Festival da Canção 2009 in order to select its entry for the contest. The competition took place on 28 February 2009 where "Todas as ruas do amor" performed by Flor-de-Lis emerged as the winner after achieving the highest score following the combination of votes from twenty regional juries and a public televote.

Portugal was drawn to compete in the first semi-final of the Eurovision Song Contest which took place on 12 May 2009. Performing during the show in position 16, "Todas as ruas do amor" was announced among the 10 qualifying entries of the first semi-final and therefore qualified to compete in the final on 16 May. It was later revealed that Portugal placed eighth out of the 18 participating countries in the semi-final with 70 points. In the final, Portugal performed in position 6 and placed fifteenth out of the 25 participating countries with 57 points.
