Erasmo Carlos (born Erasmo Esteves on June 5, 1941) is a Brazilian singer and songwriter, most closely associated with his friend and longtime collaborator Roberto Carlos (no relation). Together, they created many chart hits including "É Proibido Fumar", "Sentado à beira do caminho", "Além do Horizonte", "Amigo" and "Festa de Arromba".

A core member of the Jovem Guarda ("Young Guard") scene of 1960s Brazilian pop-rock, Erasmo often appeared on television, in magazines and feature films with fellow teen idols Roberto Carlos and Wanderléa.
