Archbishop Stepinac High School is an all-boys Roman Catholic high school in White Plains, New York, United States. It was operated by the Roman Catholic Archdiocese of New York until the 2009–2010 school year, when it became independent. It was founded in 1948 and named for Aloysius Stepinac, the Archbishop of Zagreb in Croatia, which was then part of Yugoslavia. In 1952, Stepinac was appointed a cardinal by Pope Pius XII, and was beatified by Pope John Paul II in 1998.
