St. Petersburg Catholic High School is a private, co-educational Roman Catholic high school in St. Petersburg, Florida. It is located in the Roman Catholic Diocese of Saint Petersburg. The campus was originally opened in February 1957 as Bishop Barry High School for boys. In 1973, Bishop Barry High School and the nearby Notre Dame Academy for girls merged to become St. Petersburg Catholic High School. (A decade earlier, St. Paul's High School for girls was merged into Notre Dame Academy.)
