Stanislaus of Szczepanów (Polish: Stanisław ze Szczepanowa; 26 July 1030 – 11 April 1079) was a Polish Catholic prelate who served as Bishop of Kraków and was martyred by the Polish King Bolesław II the Bold. He is the patron saint of Poland.
Stanislaus is venerated in the Catholic Church as Stanislaus the Martyr (as distinct from the 16th-century Jesuit, Stanislaus Kostka).
