Felicitas Gómez Martínez de Mendez (February 5, 1916 – April 12, 1998) was a Puerto Rican activist in the American civil rights movement. In 1946, Mendez and her husband Gonzalo led an educational civil rights battle that changed California and set an important legal precedent for ending de jure segregation in the United States. Their landmark desegregation case, known as Mendez v. Westminster, paved the way for meaningful integration and public school reform.
