Slovenia participated in the Eurovision Song Contest 2012 with the song "Verjamem" written by Vladimir Graić, Hari Mata Hari and Igor Pirkovič. The song was performed by Eva Boto. Songwriter Hari Mata Hari represented Bosnia and Herzegovina in the Eurovision Song Contest 2006 with the song "Lejla" where he placed third in the grand final of the competition. Slovenian broadcaster Radiotelevizija Slovenija organised the national final Misija EMA 2012 in order to select the Slovenian entry for the 2012 contest in Baku, Azerbaijan. 32 performers competed in the first stage of the national final, Misija Evrovizija, from which two artists qualified to compete in Misija EMA 2012 following a five-month-long competition. In Misija EMA 2012, the winner was selected over two rounds of voting. In the first round, each artist performed three songs and one song were selected for each performer following the combination of votes from a four-member jury panel and a public televote. In the second round, "Verjamem" performed by Eva Boto was selected as the winner entirely by a public televote.

The Eurovision Song Contest 2012 was the 57th edition of the Eurovision Song Contest. It took place in Baku, Azerbaijan, following the country's victory at the 2011 contest with the song "Running Scared" by Ell and Nikki. It was the first time Azerbaijan hosted the contest – only four years after the country made its debut. Organised by the European Broadcasting Union (EBU) and host broadcaster İctimai Television (İTV), the contest was held at the Baku Crystal Hall, and consisted of two semi-finals on 22 and 24 May, and a final on 26 May 2012. The three live shows were presented by Azerbaijani television presenter Leyla Aliyeva, newsreader Nargiz Birk-Petersen and singer Eldar Gasimov, the latter of whom was one of the previous edition's winners.
