The Eurovision Song Contest 2011 was the 56th edition of the Eurovision Song Contest. It took place in Düsseldorf, Germany, following the country's victory at the 2010 contest with the song "Satellite" by Lena. Organised by the European Broadcasting Union (EBU) and host broadcasters Arbeitsgemeinschaft Rundfunkanstalten Deutschland (ARD) and Norddeutscher Rundfunk (NDR), the contest was held at the Düsseldorf Arena and consisted of two semi-finals on 10 and 12 May, and a final on 14 May 2011. The three live shows were presented by German comedians Anke Engelke and Stefan Raab, and television presenter Judith Rakers.

The Eurovision Song Contest, often known simply as Eurovision, 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.
