Ana de Castro Osório (18 June 1872 – 23 March 1935) was a Portuguese feminist, active in the field of children's literature and political Republicanism.

Early life Osório was born into a well-off family on 18 June 1872, her mother being Mariana Osório de Castro Cabral e Albuquerque and her father Judge João Baptista de Castro. She was influenced by her parents immense library and became a writer by age 23. This work was reflected on educated women's increasingly strong political consciousness and the involvement of women's organizations and feminism in Republicanism. The group called for the overthrow of the monarchy and contributed to the proclamation of the Portuguese Republic in 1910. In 1911, Osório headed the Associação de Propaganda Feminista (Portuguese Feminist Propaganda Association) which was founded by Adelaide Cabete and Carolina Beatriz Ângelo.

In 1917, Osório was one of the founders of the Crusade of Portuguese Women which encouraged women to be active in the war effort.
