Rambo Amadeus (Serbian Cyrillic: Рамбо Амадеус, born Antonije Pušić, June 14, 1963) is a Belgrade-based Montenegrin singer-songwriter. A self-titled "musician, poet, and media manipulator", he is a popular phenomenon on the music scenes of the former Yugoslavia.

His songs combine satirical lyrics on the nature of common people and silliness of local politics. He uses a mixture of musical styles including jazz and rock (converging towards drum and bass lately), and self-conscious ironic wit (for example, his most popular alias is "Rambo Amadeus Svjetski Kilo Car"— "Rambo Amadeus the World Kilo Tzar", formerly "Rambo Amadeus Svjetski Mega Car"— "Rambo Amadeus the World Mega Tzar" (RASMC) (changed in 2012 because of his belief in the importance of modesty in an environmentally conscious society)). His stage name itself is made from John Rambo and Wolfgang Amadeus Mozart. Known also as a "charming king of jovial pop", his concerts are never mere repetitions of recorded songs, but a mixture of musical improvisation and humor exploiting all aspects of human nature in a crude manner. Some fans compare his style and career path with Frank Zappa.
