The Sanremo Music Festival 1985 (), officially the 35th Italian Song Festival (), was the 35th annual Sanremo Music Festival, held at the Teatro Ariston in Sanremo, Italy, between 7 and 9 February 1985 and broadcast by (RAI). The show was hosted by Pippo Baudo, assisted by Patty Brard.
The winner of the Big Artists section was Ricchi e Poveri with the song "Se m'innamoro", while Matia Bazar won the Critics Award with the song "Souvenir". Cinzia Corrado won the Newcomers section with the song "Niente di più".
Claudio Baglioni was invited as a guest to receive the "Italian Song of the Century" award for his hit "Questo piccolo grande amore". The singer-songwriter was the only artist, in this edition dominated by the play-back, to perform live (with the same award-winning song), accompanying himself on the piano alone.
