Neumann Preparatory School (known familiarly as Neumann Prep) was a private, Catholic college-preparatory school located in Wayne, New Jersey, within the Roman Catholic Diocese of Paterson.

It was founded as The Blessed John Neumann Preparatory Seminary in 1965.

In 1970 Neumann was designated a Preparatory School and was all-male until the 1974–1975 academic year.

Since then the campus has been the site of a Montessori school and the Lakeview Learning Center.
