Rosa Lúcia Benedetti Magalhães (born January 8, 1947 in Rio de Janeiro) is a Brazilian professor and artist. She is best known as the most successful carnival designer in Rio de Janeiro, with six championships won since 1984, when the Sambadrome Marquês de Sapucaí was built. Designing carnival parades since 1971, Rosa likes telling historic events in her designs, such as the discovery of Brazil (2000), the life and creations of Hans Christian Andersen (2005), Don Quixote (2010), and the corruption scandal that led to the construction of the Versailles Palace in France (2017).
