Benedictine Academy was a Catholic parochial, college preparatory high school that served young women in ninth through twelfth grades in Elizabeth, in Union County, New Jersey, United States. The school was opened in 1915 by the Benedictine Sisters of Elizabeth, Saint Walburga Monastery, and operates under the auspices of the Roman Catholic Archdiocese of Newark. In the wake of declining enrollment, the school announced that it would close at the end of the 2019–20 school year. Compared to an enrollment in 2014-15 of 174 students, the school estimated that 2020-21 enrollment would be 115.
