Esperanza López Mateos (January 8, 1907 – September 19, 1951) was a Mexican translator, political activist, syndicalist, and mountaineer. She translated several of B. Traven's novels and was his literary agent in Latin America from 1941 to 1951. She was the sister of politician Adolfo López Mateos and sister-in-law of cinematographer Gabriel Figueroa. She participated in the strike by the miners of Nueva Rosita (1950–1951) and worked with Vicente Lombardo Toledano; together they supported many Jewish exiles fleeing European wars and seeking refuge in Mexico.
