Humberto Duarte Mauro (30 April 1897 – 5 November 1983) was a Brazilian film director.

Braza Dormida was a boxoffice success and furthered Mauro's career as one of Brazil's leading directors.

Adhemar Gonzaga offered Mauro a directing job for Cinédia, which was centered in Rio de Janeiro.

Gonzaga had started to shoot Lábios sem Beijos (Lips Without Kisses) which starred Carmen Santos.

Gonzaga handed the project over to Mauro, who both directed and photographed the film, in March 1930.

In 1936, Mauro joined the Instituto de Nacional do Cinema Educativo (INCE), which was then the government office for educational and propaganda films.

His final film was Carro de Bois (Ox Cart), a documentary, in 1974.
