Gigliola Cinquetti (b. 20 December 1947 in Verona, Italy) is an Italian singer.

At the age of 16 she won the San Remo Music Festival in 1964 singing “Non ho l’età” (I’m not old enough), with music composed by Nicola Salerno and lyrics by Mario Panzeri. Her victory enabled her to represent Italy in the Eurovision Song Contest 1964 with the same song, and she went on to claim her country’s first-ever victory in the event and achieve the first UK Top 20 hit with a non-English-language Eurovision song. In 1966, she recorded “Dio, come ti amo” (God, how I love you), which became a world-wide hit. In 1974, she returned to the contest, again representing Italy, and finished second behind Sweden’s ABBA with the song “Sì” (Yes), the music and lyrics of which were written by Mario Panzeri, Daniele Pace, Lorenzo Pilat, and Carrado Conti. When translated into English as “Go”, this song reached the UK Top 10.

Gigliola went on to co-host the Eurovision Song Contest 1991 with Toto Cutugno, who had brought the event to Italy with his victory in Zagreb the previous year - the country’s first win in the contest since her own twenty-six years earlier.
