Belén de Sárraga Hernández (Valladolid 1874 – Mexico 1951) was a Spanish feminist of the Federal Republican Party.
She criticised the General for the execution of the poet and the hero of the Philippine Independence, José Rizal.
Belén and her parents moved to Puerto Rico in 1880 and advised by her grandfather Fernando Ascensión de Sárraga y Aguayo (previous Education Director from San Juan de Puerto Rico School) she studied a teaching degree.
Not long after, Belén began to gain recognition in the spheres of oratory and press, after writing numerous articles in Barcelona and Madrid magazines.
The fame and acts of Belén Sárraga de Ferrero —as she was known then—, made her rise quickly: She studied and graduated as a doctor at the University of Barcelona.
In the university, Belén organized a protest against the removal of Odón de Buen from the professorship.
She was also a contributor with the spiritual magazine La Luz del Porvenir de Barcelona.
Belén was an enthusiastic reader of works of Pierre-Joseph Proudhon, Mikhail Bakunin and Piotr Kropotkin, and proclaimed herself a spiritual daughter of Pi y Margall, Eduardo Benot and Nicolás Estévanez, Olimpia Gouges, Madame de Stäel, George Sand y Louise Miche The fame of Belén remained for fifteen years, but her marriage was in crisis, since the role of Emilio gradually became just "the husband of Belén Sárraga", which broke down the fraternal, secular and Republican ideal that was beginning to be maintained.
One year later, in Barcelona, she founded the Asociación de Mujeres Librepensadoras, which was forbidden by the governor and that is why she was arrested.
