Oratory Preparatory School, commonly known as Oratory Prep, is a Roman Catholic college preparatory day school for boys in grades 7-12, located in Summit, in Union County, New Jersey, United States, approximately 19 miles (31 km) west of Manhattan. The school is located one block away from the Kent Place School and is in close proximity to Summit High School.

The school is associated with the Roman Catholic Archdiocese of Newark. Oratory Preparatory School is a member of the New Jersey Association of Independent Schools. The school has been accredited by the Middle States Association of Colleges and Schools Commission on Elementary and Secondary Schools since 1973.

As of the 2017–18 school year, the school had an enrollment of 373 students and 36.6 classroom teachers (on an FTE basis), for a student–teacher ratio of 10.2:1. The school's student body was 80.7% (301) White, 6.2% (23) Hispanic, 5.9% (22) Asian, 4.0% (15) two or more races and 2.9% (11) Black.

The school was founded in 1907 as Carlton Academy, with grades 4-12. Most of the students lived on campus. Due to the school's relatively small size, students in a given grade are not individually ranked. Oratory is home to young men from more than 70 communities in the New York metro area. Tuition for the 2018-19 academic year was $22,350 and a $300 registration fee is required; this does not include costs for transportation, books and meals. Each year 100% of Oratory seniors are accepted to four-year colleges.
