"Nel blu, dipinto di blu" (Italian pronunciation: [nel ˈblu diˈpinto di ˈblu]; 'In the blue [sky] [as I was] painted blue' or 'In the blue-painted blue [sky]'), popularly known as "Volare" (pronounced [voˈlaːre]; 'To fly'), is a song originally recorded by Italian singer-songwriter Domenico Modugno. Written by Modugno and Franco Migliacci, it was released as a single on 1 February 1958.

The song spent five non-consecutive weeks atop the Billboard Hot 100 in August and September 1958, and subsequently became Billboard's number-one single for the year. In 1959, at the 1st Annual Grammy Awards, Modugno's recording became the first ever Grammy winner for both Record of the Year and Song of the Year.

Dean Martin included a half-English version of the song, with lyrics adapted by Mitchell Parish, on his LP This Is Dean Martin!.
