Carmen Lucia (April 2, 1902 – February 19, 1985) was a union organizer in the United States, nicknamed the "Hatter's Fighting Lady".
She took support classes from the YWCA, which led to her getting recruited to the Bryn Mawr Summer School for Women Workers in 1927.
Throughout the 1930s, Lucia was jailed and beaten multiple times while organizing protests and strikes.
She was at the time an organizer for the Cap makers International Union, and had the protesters carry their babies on their shoulders and hand out pamphlets reading "Take our mothers off the streets.
She served as a chair on a number of boards, including the Georgia State Federation of Labor.
