Portugal in the Eurovision Song Contest 2001

Portugal was represented at the Eurovision Song Contest 2001 with the song "Só sei ser feliz assim" written by Marco Quelhas and performed by the duo MTM. The Portuguese participating broadcaster, Radiotelevisão Portuguesa (RTP), returned to the Eurovision Song Contest after a one-year absence following their relegation in 2000 as one of the six countries with the lowest average scores over the previous five contests. RTP organised the national final Festival da Canção 2001 in order to select its entry for the contest. After five semi-finals and a final which took place between October 2000 and March 2001, "Só sei ser feliz assim" performed by MTM emerged as the winner after achieving the highest score following the combination of votes from 20 regional juries.

The song competed in the Eurovision Song Contest which took place on 12 May 2001. Performed during the show in position 11, it placed seventeenth out of the 23 participating songs from different countries, scoring 18 points.
