Titãs (Portuguese pronunciation: [tʃiˈtɐ̃s], Portugese for Titans) are a Brazilian rock band from São Paulo. Though they primarily are classified as a rock band, the band have also experimented with genres such as new wave, punk rock, ska, grunge, MPB and electronic music. They are one of the most successful rock bands in Brazil, having sold more than 6.3 million albums as of 2005 and having been covered by several well-known Brazilian artists and a couple of international singers. They were awarded a Latin Grammy in 2009 and have won the Imprensa Trophy for Best Band a record four times.

Titãs is known for initially having nine members: bassist and vocalist Nando Reis, vocalists Branco Mello, Ciro Pessoa, and Arnaldo Antunes, guitarist Marcelo Fromer, vocalist and guitarist Tony Bellotto, multi instrumentalist and vocalist Paulo Miklos, drummer André Jung, and keyboardist and vocalist Sérgio Britto, with the members alternating between lead and backing vocals. Pessoa left the band before their debut album, Titãs, was released, while Jung was replaced by Charles Gavin in 1985, establishing their principal line-up.

As of 2024, Mello, Bellotto, and Britto are the only members still performing under the Titãs name: Antunes departed the band in 1992 to pursue a solo career. In 2001, Fromer was killed by a motorcycle in São Paulo, while Reis left the group the year after to focus on solo endeavors. Gavin departed the band in 2010 due to personal reasons, and Miklos departed the band in 2016 to focus on solo projects. Since their departures, the band have utilized numerous session and touring musicians in place of the band's former members, most notably Rita Lee's son Beto Lee and drummer Mario Fabre. From 2023 to 2024, Antunes, Reis, Gavin, and Miklos rejoined the band as touring musicians.

The band has released their latest studio album in 2022, titled Olho Furta-Cor.
