Sweden in the Eurovision Song Contest 2012

Sweden was represented at the Eurovision Song Contest 2012 with the song "Euphoria", written by Thomas G:son and Peter Boström, and performed by Loreen. The Swedish participating broadcaster, Sveriges Television (SVT), organised the national final Melodifestivalen 2012 in order to select its entry for the contest. After a six-week-long competition consisting of four heats, a Second Chance round and a final, "Euphoria" performed by Loreen emerged as the winner after achieving the highest score following the combination of votes from eleven international jury groups and a public vote.

Sweden was drawn to compete in the second semi-final of the Eurovision Song Contest which took place on 24 May 2012. Performing during the show in position 11, "Euphoria" was announced among the top 10 entries of the second semi-final and therefore qualified to compete in the final on 26 May. It was later revealed that Sweden placed first out of the 18 participating countries in the semi-final with 181 points. In the final, Sweden performed in position 17 and placed first out of the 26 participating countries, winning the contest with 372 points. This was Sweden's fifth win in the Eurovision Song Contest, having previously won in 1974, 1984, 1991, and 1999.
