Hackley School is a private college preparatory school located in Tarrytown, New York, and is a member of the Ivy Preparatory School League. Founded in 1899 by a wealthy philanthropist, Frances Hackley, the school was intended to be a Unitarian alternative to Episcopal boarding schools. Since its founding, Hackley has dropped its Unitarian affiliations and changed from all-boys to coeducational.
The current Head of School is Charles Franklin.
