Russia participated in the Eurovision Song Contest 2007 in Helsinki, Finland. Despite early indications that the Russian participation for 2007 would be organised by Rossiya Channel (RTR), Channel One Russia (C1R) remained in charge of selecting the Russian entry and retained the broadcast rights for the 2007 Contest. The Russian entry was selected internally by C1R. Serebro represented Russia with the song "Song #1", which placed 3rd in the final, scoring 207 points.

Serebro was a Russian girl group formed by their manager and producer Maxim Fadeev. Serebro was formed in 2007, consisting of Marina Lizorkina, Olga Seryabkina, and Elena Temnikova as a submitted proposal for consideration by Channel One Russia for the Eurovision Song Contest 2007. Serebro was selected to represent Russia at the 2007 Contest with the song titled "Song #1". They subsequently placed third at the contest, scoring a total of 207 points. Serebro was then officially signed to Fadeev's record label Monolit Records, and in 2012, the group had additional releases produced by Sony Music Entertainment and Ego Music. In 2009, Lizorkina announced her departure from the group; she was subsequently replaced by Anastasia Karpova. Karpova left the group in 2013 and was replaced by Dasha Shashina, who left in 2016. Temnikova left the group in 2014 due to health reasons, and Polina Favorskaya, who replaced Temnikova, left the group in 2017. Favorskaya was later replaced by Morgunova. In 2019, the line-up Olga Seryabkina, Katya Kischuk, and Tatiana Morgunova, the last one to include the last original member, has been replaced by Elizaveta Kornilova, Marianna Kochurova and Irina Titova.
