Portugal in the Eurovision Song Contest 2006

Portugal was represented at the Eurovision Song Contest 2006 with the song "Coisas de nada" written by José Manuel Afonso and Elvis Veiguinha, and performed by the group Nonstop. The Portuguese participating broadcaster, Rádio e Televisão de Portugal (RTP), organised the national final Festival da Canção 2006 in order to select its entry for the contest. The competition took place on 11 March 2006 where "Coisas de nada" performed by Nonstop emerged as the winner after tying for first place following the combination of votes from five-member jury panel and a public televote—the tie was decided in Nonstop's favour after their song scored the highest with the jury.

Portugal competed in the semi-final of the Eurovision Song Contest which took place on 18 May 2006. Performing during the show in position 19, "Coisas de nada" was not announced among the top 10 entries of the semi-final and therefore did not qualify to compete in the final. It was later revealed that Portugal placed nineteenth out of the 22 participating countries in the semi-final with 26 points.
