Raul Santos Seixas (Portuguese pronunciation: [ʁaˈuw ˈsejʃɐs]; 28 June 1945 – 21 August 1989) was a Brazilian rock musician foundational to the genre. Rolling Stone Brazil named Seixas among the greatest artists in Brazilian music.

Throughout his career, Seixas composed music in several genres, blending rock'n'roll, folk, and ballads with variations of Northeastern Brazil rhythms like forró, baião, and xote. His 1968 debut album, Raulzito e os Panteras, was produced when he was part of a band of the same name.

Several Raul Seixas songs emphasized philosophical, spiritual and mystical themes; his album Gita (1974) was influenced by figures such as Aleister Crowley. Several of his songs were co-written with future author Paulo Coelho.
