Adelina Zendejas (16 December 1909 – 4 March 1993) was a Mexican teacher, journalist and feminist, who was one of the first writers to discuss gender inequality and the social status of women in the country.

[1] As a child, Zendejas wanted to study medicine and was encouraged by her father, a railroad worker and activist and her maternal great-grandfather, Joaquín Eguía Lis [es], a Catholic intellectual and the first rector of the National University of Mexico, before it gained its autonomy.

[3] Among her classmates were Frida Kahlo, Carmen Jaime, Alejandro Gómez Arias, Agustín and Miguel N. Lira, Alfonso Villa, and José Zález Ramírez.

[4] Teaching was an expected occupation for women at the time, though her university degree rather than a normal school license was unusual, as was her work in journalism, a field dominated by men in that era.

[6] In 1935, the Frente Único Pro Derechos de la Mujer [es] (Single Front for Women's Rights, FUPDN) was formed and Zendejas along with others joined the organization.

FUPDN's main goals were to fight against fascism and imperialism, support an eight-hour work day, provide agricultural reform and social security, and improve women's lives through health initiatives, full citizenship and the vote.

She recovered the history of the FUPDN, and the women involved in it, like Ester Chapa, Cuca García, Concha Michel and Josefina Vicens, all of whom played a critical role in the social reforms which took place in the post-Revolutionary development of the country.
