Maidens' Tower (also translated as The Virgin's Tower and known as Torre das Donzelas in Brazilian Portuguese) is a 2018 Brazilian documentary film, lasting 97 minutes and directed by Susanna Lira, who defined the film as a call to resistance .

Maidens' Tower discusses and denounces the cruel and brutal experiences to which women prisoners were subjected during the period of the Brazilian Military Dictatorship (1964–1985), through the reports of several persecuted and imprisoned women, of which the former Brazilian president, Dilma Rousseff, stands out. In this film, women who are former political prisoners describe their daily lives: from cleaning their cells to the importance of reading in maintaining hope, the torture they suffered and how they were captured in their fight for democracy. The film recreated, based on the memoirs of former inmates, a scenario similar to the prison. The Tiradentes Prison, which housed the Maidens Tower (as part of the women's prison), was demolished in 1972

Maidens' Tower premiered on September 25, 2019, at Cine Metrópolis, at Ufes and was attended by Dilma Rousseff. After its theatrical debut, it had its television premiere on April 22, 2020, on Canal Brasil.
