Vox Dei (Latin, 'Voice of God') is an Argentine rock band credited for recording the country's first concept album, La Biblia. Their most prolific years were the 1970s, when they recorded ten albums.

Vox Dei have had several line-up changes and a five-year hiatus. Their third and most commercially successful line-up featured Ricardo Soulé (guitar and vocals), Willy Quiroga (bass and vocals) and Rubén Basoalto (drums). This line-up was active from 1972 to 1974 (then in 1978 to the 1981 break-up), and was revived from 1986 to 1989, and again from 1996 to 1998. The band's line-up (currently featuring Willy Quiroga, and guitarist Carlos Gardellini from 1992) has been much more stable in recent years, although drummer Rubén Basoalto's death in 2010 (being succeeded by Simon Quiroga) left Willy Quiroga as the only original member still in the band.
