Oswaldo Baptista Fadda (January 15, 1921 – April 1, 2005) was a practitioner of Brazilian Jiu-Jitsu, reaching the rank of "nono grau", a ninth grade red belt. He is known for being one of the highest ranked non-Gracie black belts and also for teaching students from the poorer areas of Rio de Janeiro, where jiu-jitsu was regarded as an upper-class sport. Fadda's lineage, the most prominent second to the Carlos Gracie lineage, still survives through his links with today's teams such as Nova União, Grappling Fight Team, as well as Deo Jiu-Jitsu (Deoclecio Paulo) and Equipe Mestre Wilson Jiu-Jitsu (Wilson Pereira Mattos).
