Eurovision Song Contest 1957

The Eurovision Song Contest 1957, originally known as the Grand Prix Eurovision de la Chanson Européenne 1957 (English: Eurovision Grand Prize of European Song 1957), was the second edition of the Eurovision Song Contest, held on Sunday 3 March 1957 at the Großer Sendesaal des Hessischen Rundfunks in Frankfurt, West Germany, and presented by Anaid Iplicjian. It was organised by the European Broadcasting Union (EBU) and host broadcaster Hessischer Rundfunk (HR) on behalf of ARD.

Broadcasters from ten countries participated in the contest, with Austria, Denmark, and the United Kingdom competing for the first time and joining the original seven participating countries from the first contest in 1956.

The winner of the contest was the Netherlands, with the song "Net als toen" performed by Corry Brokken. This was Brokken's second appearance as a participant, after previously representing the Netherlands in 1956; her victory marked the first of five Dutch wins in the contest as of 2025. France, Denmark, Luxembourg and Germany rounded out the top five.

A number of changes to the rules from the previous year's event were enacted; each country were now represented by only one song, while the voting system received an overhaul, with the results of the voting now conducted on a scoreboard in view of the public to allow the process to be followed by viewers and listeners at home. Jurors were also no longer allowed to vote for the song from their own country.
