Sérgio Ricardo, stage name of João Lutfi (born in Marília, São Paulo, June 18, 1932 - died July 23, 2020, Rio de Janeiro, heart failure), was a Brazilian singer, composer and award-winning film director.

In 1957 he recorded his first 78 rpm through RGE, soon followed by another. It was then, when Maysa (Maysa Matarazzo) heard one of his compositions and recorded Buquê de Isabel on one of her first albums. Accompanying the singer on a TV show, he was invited to join the station as a soap opera actor. He continued to work both in music and on TV.

In the late 50s he became part of the first group of composers of the Bossa nova movement and released one of the first Bossa Nova albums (Não Gosto Mais de Mim/ A Bossa romãntica in 1960). Soon after he began to take notice of political and social problems, which led him to compose songs portraying these themes. Also his film making started to reflect this interest.

At that time he made his first short film O Menino da Calça Branca (22 min., 1961), which won several awards on film festivals in 1962. Longer award winning films followed during the next years: Esse Mundo É Meu (1964), Juliana Do Amor Perdido (1968) and A Noite Do Espantalho (1973).

During his film projects he always found time to record more albums. He recorded successfully many soundtracks for movies and TV-plays, again well received by the different film festivals. In 1991, he released his book Quem Quebrou meu Violão. He was also a painter.
