Stanislaus Kostka, Polish saint (d. 1568)
Stanisław Kostka S.J. (28 October 1550 – 15 August 1568) was a Polish novice of the Society of Jesus. He is venerated in the Catholic Church as Saint Stanislaus Kostka (as distinct from his namesake, the 11th-century Bishop of Kraków Stanislaus the Martyr).

He was born at Rostkowo, Przasnysz County, Poland, on 28 October 1550, and died in Rome during the night of 14–15 August 1568. He entered the Society of Jesus in Rome on his 17th birthday (28 October 1567), and is said to have foretold his death a few days before it occurred.
