Portugal in the Eurovision Song Contest 2010

Portugal was represented at the Eurovision Song Contest 2010 with the song "Há dias assim" written by Augusto Madureira, and performed by Filipa Azevedo. The Portuguese participating broadcaster, Rádio e Televisão de Portugal (RTP), organised the national final Festival da Canção 2010 in order to select its entry for the contest. After two semi-finals and a final which took place in March 2010, "Há dias assim" performed by Filipa Azevedo 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 25 May 2010. Performing during the show in position 14, "Há dias assim" was announced among the top 10 entries of the first semi-final and therefore qualified to compete in the final on 29 May. It was later revealed that Portugal placed fourth out of the 17 participating countries in the semi-final with 89 points. In the final, Portugal performed in position 23 and placed eighteenth out of the 25 participating countries with 43 points.
