Oficina G3 is a christian rock band from São Paulo, São Paulo, Brazil. Formed in 1988, the current band's line-up consists of: Mauro Henriques (vocals), Juninho Afram (guitars), Jean Carllos (keyboards) and Duca Tambasco (bass). As of 2006, Celso Machado and Alexandre Aposan occasionally tours with the band, playing rhythm guitar and drums, respectively.

The band began its work in 1988, as the musical group of the protestant church Cristo Salva. Juninho Afram is the only founding member who still plays in the band. In 1990, Oficina G3 released its first EP.

In 1993, they released their first full-length album, called Nada é Tão novo, Nada é Tão velho (Nothing is so new, Nothing is so old). Two new musicians (Duca and Jean) entered to the band, in addition to the departure of founding member and bass player Wagner Garcia. In 1996, they released Indiferença (Indifference), which was followed in 1998 by an Acoustic album.

Probably the band's best moment was in 2000s, when they met the vocalist PG (currently on solo career) and relased O Tempo (The Time) in 2000 and Humanos (Humans) in 2003. Walter Lopes, founding member and drummer, left the band in 2002, in order to begin a pastoral ministry, while PG would leave the band one year later, to pursue his own career. Juninho assumed the vocals. In 2005, Além do que os Olhos Podem Ver (Beyond the eyes can see) was released, the first album featuring Juninho Afram on lead vocals.

They're now touring and promoting their newest album, Depois Da Guerra (After the War), released in 2008.
