María del Tránsito Cabanillas was an Argentine religious sister born in 1821. Following the death of her mother, she joined the Third Order of Saint Francis in 1859. After brief periods in Carmelite and Visitation convents, she established her own congregation, the Franciscan Tertiary Missionary Sisters, to focus on educating children and assisting the poor. She died in San Vicente in 1885. Recognized for her heroic virtue, she was beatified by the Catholic Church in 2002.
