María Guggiari Echeverría Santos was a Paraguayan Discalced Carmelite nun who lived from 1925 to 1959. Born in Villarrica, she was active in the Catholic Action movement during her youth, where she served as a catechist and assisted the poor. After discerning her vocation, she entered the Order of Discalced Nuns of the Blessed Virgin Mary of Mount Carmel in 1955. She died in Asunción at a young age following an illness, leaving a legacy of religious devotion that eventually led to her recognition by the Catholic Church.
