Matheus & Kauan is a Brazilian musical duo consisting of brothers Matheus Aleixo Pinto Rosa (born October 4, 1994) and Osvaldo Pinto Rosa Filho (born December 7, 1988). They perform sertanejo and pop music. Since 2010, the duo has recorded original songs and written songs for other Brazilian musicians. They became prominent in 2015 when their version of the Paula Matto song "Que Sorte a Nossa" reached over 200 million views on YouTube.

The duo composes their own songs but often collaborates with other artists, including "Tudo que Você Quiser" with Luan Santana, "Se Tudo Fosse Fácil" with Michel Teló, and "Coisas de Quem Ama" covered by Jorge & Mateus. Their hit "Ao Vivo e a Cores" with Brazilian singer Anitta stayed at the top of the Spotify Brazil list for almost two months.
