Maria Consolata Betrone (6 April 1903 – 18 July 1946), baptised as Pierina Maria Betrone and commonly known as Sister Consolata Betrone, was a Catholic mystic and nun of the Franciscan Capuchine order.
Betrone was born in Saluzzo, Piedmont, Italy, in a middle-class family.
She died at the convent of Moriondo, Testona, Italy.
Betrone was known for the intense propagation of the rosary, along with reputed apparitions by the Sacred Heart of Jesus and her guardian angel in 1916 during the Feast of the Immaculate Conception.
The reputed messages asked for the recitation of: "Jesus, Mary, I love you! Save Souls!", an ejaculatory prayer which Betrone said to release souls from Purgatory and to pardon 1000 blasphemies against the Sacred Heart of Jesus.
The pious devotion is very popular among Filipino and Portuguese Catholics, who include invocations in their recitation of the rosary along with the Fatima Prayer.
