Switzerland in the Eurovision Song Contest 1957

After their win in 1956, Switzerland continued with their format of a national final to select their entry for the 1957 contest.

National final
The final was held on 11 February 1957 in St. Moritz. Three artists competed to represent Switzerland: last year's winner Lys Assia; Jo Roland, who participated at the national final of 1956; and Gianni Ferraresi, and the winning song was chosen by the votes of 4 regional juries. The winner was Lys Assia for the second year, with the song "L'enfant que j'étais".

The winning title was written by Émile Gardaz and composed by Géo Voumard, the same duo who wrote the previous year's Swiss entry and Eurovision winner "Refrain".
