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.

The Eurovision Song Contest, often known simply as Eurovision or by its initialism ESC, is an international song competition organised annually by the European Broadcasting Union. Each participating country submits an original song to be performed live and transmitted to national broadcasters via the Eurovision and Euroradio networks, with competing countries then casting votes for the other countries' songs to determine a winner.
