Father Christopher Szwernicki (listen) (September 8, 1814 – November 26, 1894) was a priest of the Congregation of Marian Fathers.
In 1849, he was deported to Irkutsk, where he worked until his death as a parish priest of the largest parish in the world (which occupied all of Siberia from the Arctic Ocean to China).
In 1888 he was dubbed "Apostle of Siberia" by Pope Leo XIII.
