Lithuania in the Eurovision Song Contest 2004

Lithuania participated in the Eurovision Song Contest 2004 with the song "What's Happened to Your Love?" written by Michalis Antoniou, Linas Adomaitis and Camden-MS. The song was performed by Linas and Simona. The Lithuanian broadcaster Lithuanian National Radio and Television (LRT) returned to the Eurovision Song Contest after a one-year absence following their relegation from 2003 as one of the bottom five countries in the 2002 contest. LRT organised the national final "Eurovizijos" dainų konkurso nacionalinė atranka (Eurovision Song Contest national selection) in order to select the Lithuanian entry for the 2004 contest in Istanbul, Turkey. The national final took place over seven weeks and involved 52 competing entries. In the final, eighteen entries remained and "What's Happened to Your Love?" performed by Linas and Simona was selected as the winner by the combination of votes from a jury panel and a public vote.

Lithuania competed in the semi-final of the Eurovision Song Contest which took place on 12 May 2004. Performing during the show in position 12, "What's Happened to Your Love?" 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 Lithuania placed sixteenth out of the 22 participating countries in the semi-final with 26 points.
