Skylab, also retroactively referred to as Skylab I, is the second studio album by the Brazilian musician Rogério Skylab, the first in his series of ten eponymous, numbered albums. It was self-released in 1999 and produced by Robertinho do Recife, who also played the guitar and did the musical arrangements. The album is notable for containing Skylab's most famous composition, "Matador de Passarinho", among other hits which became staples of his live performances, such as "Motosserra", "Matadouro de Almas", "Funérea" and "Naquela Noite", the latter a re-recording from his previous album, Fora da Grei. "Pedigree" was re-recorded twenty-three years later for Caos e Cosmos, Vol. 2. A music video for "No Cemitério" was released on December 31, 2025.
