Tizuka Yamasaki (born May 12, 1949) is a Brazilian film director. Daughter of Japanese immigrants, Yamasaki was one of the first women filmmakers in Brazil to achieve a successful and longstanding career. She and her peers learned filmmaking by working on the sets of well-established Cinema Novo directors such as Glauber Rocha and Nelson Pereira dos Santos.

Yamasaki challenged the norms of Cinema Novo by increasing both the representation of women and the awareness of issues affecting women in Brazilian society. Her film style focuses on historical subjects and she uses the genre of melodrama to reconstruct Brazilian politics, history and culture.
