Blessed Caius of Korea (born 1571 in Korea– died 15 November 1624 in Nagasaki, Japan) is the 128th of the 205 Roman Catholic Martyrs of Japan beatified by Pope Pius IX on 7 July 1867, after he had canonized the Twenty-six Martyrs of Japan five years before on 8 June 1862. The 19th century French Catholic missionary Claude-Charles Dallet wrote of him in his A history of the church in Korea, "His history proves, in a dazzling way, that God would rather make a miracle than abandon an infidel who follows the lights of his conscience, and seeks the truth with an upright and docile heart."
