Os Nazaritos, formerly called Os Nazarenos is a Brazilian Christian rock band.

The band was formed by Gustavo Legal in 1998 in Itaguaí, in the state of Rio de Janeiro. Mixing rhythms such as ska, rock, country music and reggae, Nazaritos create a kind of comical rock in the evangelical scene. With the support of Ronaldo Barros, father of singer Aline Barros, the band signed with AB Records and released their first CD in 1999, making it a huge success in Gospel.

With the band's departure from AB Records to the Top Gospel label, the members changed the group's name to Os Nazaritos. In 2001, he performed at Rock in Rio III at Tenda Brasil together with Los Hermanos, Ls Jack among others. It was considered, by Roberto Medina himself (Creator of Rock in Rio), that the Band's presentation would be on Palco Mundo before the Iron Maiden Band's presentation.
But the band thought it would be better to perform on Teen day at Tenda Brasil as they would have more time to perform.

After long years of hiatus, the group returned to activities in 2016, for a commemorative tour, and released, in 2017, the EP O Emergente. In February 2022, Banda leader Gustavo Legal announced the Band's return to the stage.

Despite the similarities with Mamonas Assassinas, the band states that their main influences were the singer Falcão and the band Blitz, and that the association with Mamonas was marketing for the record label AB Records.
