Erasmo Carlos, born Erasmo Esteves on June 5, 1941, in the Tijuca area of Rio de Janeiro, is a Brazilian singer and songwriter, most closely associated with his friend and longtime collaborator Roberto Carlos (no relation). Together, they have created many chart hits including "É Proibido Fumar".

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.
