Sophie-Thérèse de Soubiran La Louvière was a 19th-century French nun who founded the Sisters of Marie-Auxiliatrice. Born in 1834 in Castelnaudary, she initially intended to join the Carmelites but instead dedicated herself to supporting her uncle's parish goals. After establishing her own religious community in 1864, she faced false accusations of financial misconduct that forced her to leave the order. She eventually joined the monastery of Our Lady of Charity in Paris, where she lived until her death in 1889. She was beatified by Pope Pius XII in 1946.
