Graforreia Xilarmônica is a Brazilian Prêmio Açorianos-winning rock group from Porto Alegre, Rio Grande do Sul. Famous for their humorous, unpretentious lyrics and for their sonority influenced by 1960s-era bands, the Jovem Guarda movement and traditional gaúcho music, they amassed a strong cult following throughout the 1980s and 1990s which lasts to the present day.
