Sofía Montenegro Alarcón (born 15 February 1954) is a Nicaraguan journalist, social researcher, and feminist. Montenegro's family were militarily aligned with the Somoza forces, but her feminist and Marxist studies moved her to join with the opposition to the regime. She fought in the Sandinista Revolution and though initially supportive of the Sandinista Party, later became an outspoken critic, saying it had moved to the right. She served as an editor of various divisions of the official Sandinista newspaper, Barricada, until 1994, when she founded the Center for Communication Research (CINCO) as an independent research organization free of government influence. She has written broadly on power, gender, and social interaction.
