Italo disco (sometimes hyphenated, such as Italo-disco, subjected to varying capitalization, or abbreviated as Italo) is a genre of music which originated in Italy and was mainly produced at the end of the 1970s to mid-1980s. The origin of the genre's name is strongly tied to marketing efforts of the ZYX record label, which began licensing and marketing the music outside Italy in 1982. Italo disco faded in the early 1990s.

Italo disco evolved from the then-current dance music (including hi-NRG) and developed into a diverse genre. The genre employed drum machines, synthesizers, and occasionally vocoders and was usually sung in English.
