Raphael Kalinowski (September 1, 1835 – November 15, 1907) was a Polish Carmelite friar and saint of the Catholic Church. Born in Vilnius, he worked as an engineer before joining the January Uprising in Poland, for which he was exiled to Siberia. During exile, he deepened his faith and later became a Carmelite priest, known for his humility, spiritual guidance, and mystical life. He was canonized by Pope John Paul II in 1991.
