Maria Gabriella Sagheddu was an Italian Trappist nun born in 1914 in Dorgali. A member of the Order of Cistercians of the Strict Observance, she lived a life of contemplative prayer and deep spiritual devotion. She is recognized for her intense commitment to ecumenism, having offered her life as a sacrifice to seek the unity of all Christians. After a brief period of illness, she died in 1939 in Grottaferrata. She was beatified by Pope John Paul II in 1983, who highlighted her as an exemplary model for those praying for Christian unity.
