Morristown Beard School is a coeducational, independent, college-preparatory day school located in Morristown, in Morris County, New Jersey, United States. Serving students in sixth through twelfth grades, the school has two academic units: an Upper School (9-12) and a Middle School (6-8). The present-day Morristown Beard School was formed from the 1971 merger of two single-sex schools: the Beard School for Girls and the Morristown School for Boys. The Commission on Secondary Schools at the Middle States Association of Colleges and Schools has accredited the school since 1973.
