Pope Pius XII High School

Pope Pius XII High School was a Roman Catholic high school serving students in ninth through twelfth grades located in Passaic, in Passaic County, New Jersey, United States, that had been operated by the Roman Catholic Diocese of Paterson from 1939 until it closed in 1983.

The school opened to students in September 1939. A 1957 expansion project brought the school's capacity up to 1,100 students. In the facing of declining enrollment that had fallen under 300 and rising financial deficits that could not be covered by fundraising, the Paterson diocese announced in February 1983 that the school would be closed at the end of the 1982-83 school year. Existing students would be shifted to Paterson Catholic High School and Paul VI High School.
