Teresa Ulloa

Teresa Columba Ulloa Ziáurriz (31 December 1949 – 28 September 2025) was a Mexican human rights activist. She was known for her support of female victims of sex trafficking in Mexico, including rescuing women from trafficking rings and representing them in court. Ulloa was the regional director for Latin America and the Caribbean for the Coalition Against Trafficking in Women.

Early life Ulloa was born on 31 December 1949 in Mexico City, the oldest child of Armando Ulloa, an insurance salesman, and his wife, Graciela Ziáurriz Hernández. She attended the Colegio Francés Mayorazgo and the Panamerican Workshop before graduating with a bachelor's degree in education and human relations from the Instituto Nacional de Pedagogía in 1973. As a student, she was impacted by the Mexican Movement of 1968. Beginning in the 1980s, Ulloa worked with state and federal governments to draft laws that increased punishments for rape and closed legal loopholes in existing legislation. This notably included a 2007 law protecting women from violence and a 2012 law increasing penalties for trafficking. She legally represented women and girls in over 25, 000 rape cases as of 2011.
