Maria Antonia Pereira y Andrade was an 18th-century Spanish mystic and nun of the Order of Discalced Carmelite Nuns. Born in Cuntis in 1700, she initially lived as a wife and mother, raising two children alone while her husband worked in distant cities. After years of spiritual discernment, she joined the Carmelite Third Order and eventually entered the religious life in 1733, following her husband into the same order. She is remembered for her profound spiritual writings and her successful efforts to establish a Carmelite community in Santiago de Compostela.
