The Sanremo Music Festival (Italian: Festival di Sanremo [ˈfɛstival di sanˈrɛːmo, festiˈval -]), officially the Italian Song Festival (Italian: Festival della canzone italiana), is the most popular Italian song contest and awards ceremony, held annually in the city of Sanremo, Liguria, organized and broadcast by Italian public broadcaster RAI. It is the longest-running annual TV music competition in the world on a national level (making it one of the world's longest-running television programmes) and it is also the basis and inspiration for the annual Eurovision Song Contest.

Unlike other awards in Italy, the Sanremo Music Festival is a competition for new songs, not an award to previous successes (like the Premio regia televisiva for television, the Premio Ubu for stage performances, and the Premio David di Donatello for motion pictures).

The first edition of the Sanremo Music Festival, held between 29 and 31 January 1951, was broadcast by RAI's radio station Rete Rossa, and its only three participants were Nilla Pizzi, Achille Togliani, and Duo Fasano. Starting from 1955, all editions of the festival have been broadcast live by the Italian TV station Rai 1.

From 1951 to 1976, the festival took place in the Sanremo Casino, but starting from 1977, all the following editions were held in the Teatro Ariston, except in 1990, which was held at the Nuovo Mercato dei Fiori.

The songs selected in the competition are in Italian or in any regional language, and the three most voted songs are awarded. Other special awards are also given, including the Critics' Award, created ad hoc by the press in 1982 to reward the quality of Mia Martini's song, and named after the singer in 1996, after her death.

The Sanremo Music Festival has often been used as a method for choosing the Italian entry for the Eurovision Song Contest. It has launched the careers of some of Italy's most successful musical acts, including Toto Cutugno, Gigliola Cinquetti,

Laura Pausini, Eros Ramazzotti, Andrea Bocelli, Giorgia, Il Volo, and Måneskin.

Between 1953 and 1971 (except in 1956), in 1990, and 1991, each song was sung twice by two different artists, each one using an individual orchestral arrangement, to illustrate the meaning of the festival as a composers' competition, not a singers' competition. During this era of the festival, it was custom that one version of the song was performed by a native Italian artist while the other version was performed by an international guest artist. This became a way for many international artists to debut their songs on the Italian market, including Louis Armstrong, Ray Charles, Stevie Wonder, Cher, Gloria Gaynor, Dionne Warwick, Jose Feliciano, Roberto Carlos, Paul Anka, Miriam Makeba, Bonnie Tyler, Shirley Bassey, Mungo Jerry, Kiss, Laura Branigan, Alla Pugacheva, and many others.
