"Maracatu Atômico" (Portuguese for "Atomic Maracatu") is a song written and composed by Brazilian musicians Jorge Mautner and Nélson Jacobina in 1974, and originally performed by Mautner on his self-titled album released in the same year. It is one of the duo's most famous creative outputs, thanks to the numerous cover versions it received over the years, the most famous of them being the one made by Nação Zumbi in 1996.

Pernambuco-based Mangue Bit band Nação Zumbi covered the song for their second studio album, Afrociberdelia, from 1996; it served as the album's second single. A critically acclaimed music video for the song, directed by Raul Machado, was shot in April of the same year. It was the last music video to be ever broadcast by MTV Brasil, which ceased its activities on September 30, 2013; it was hosted by former MTV VJ Cuca Lazzarotto, who also hosted the channel's first music video back in its inauguration on October 20, 1990.

In 2010, the band re-recorded the song for the soundtrack of the documentary film Senna.

Gilberto Gil was the first one to cover the song, for his 1974 album Cidade do Salvador.

In 2012, Jorge Mautner re-recorded the song alongside Pedro Sá, Alexandre Kassin, Domenico Lancellotti and Berna Ceppas for the soundtrack of the documentary Jorge Mautner: O Filho do Holocausto. In the same year, the song was also covered by singer BNegão at the closing ceremony of the London Summer Olympics.
