Archbishop Stepinac High School is an American all-boys' Roman Catholic high school in White Plains, New York.

It was operated by the Roman Catholic Archdiocese of New York until the 2009–2010 school year, when it became independent of the Archdiocese.

It was founded in 1948 and named after Aloysius Stepinac, who was the Archbishop of Zagreb in Croatia (which was then part of Yugoslavia).

In 1952, Stepinac was appointed a cardinal by Pope Pius XII. Stepinac was beatified by Pope John Paul II in 1998.
