Dina Bélanger was a Canadian musician and nun of the Religious of Jesus and Mary who lived from 1897 to 1929. Born in Quebec, she was a talented pianist who studied in the United States before entering religious life. Despite suffering from chronic illness, particularly tuberculosis, she maintained a profound spiritual life. She is remembered for her mystical experiences, which she documented in an autobiographical account written during her years of illness. She was beatified by the Catholic Church in 1993.
