Luis Gustavo Sánchez Blanco (February 2, 1934 — September 19, 2021) was a Spanish-Brazilian actor.

Born in Gothenburg, Sweden, he was the son of a Spanish diplomat, Luis Amador Sánchez Fernández, working in Sweden, and Elena Blanco Castañera, a Spanish woman. He came to live in Brazil at four years old, when his father arrived in the country to become the Spanish ambassador.

He started working as an assistant director at TV Tupi, accompanying his sister, the actress Helenita Sanches, appointed by Cassiano Gabus Mendes, the station's artistic director and his brother-in-law. Soon after, he had already participated in several films, telenovelas, and telethons until he starred as the eponymous anti-hero in the 1968 telenovela Albert, the Rockefeller. Since then he has consolidated his artistic career acting in several soap operas and films, mainly in comedy roles.
