The Juilliard School ( JOO-lee-ard), often abbreviated simply as Juilliard, is a private performing arts conservatory in New York City. Founded by Frank Damrosch as the Institute of Musical Art in 1905, the school later added dance and drama programs and became the Juilliard School, named after its principal benefactor Augustus D. Juilliard. Juilliard is one of the most prestigious performing arts schools in the world.

The school is composed of three primary academic divisions: dance, drama, and music, of which the latter is the largest and oldest. Juilliard offers degrees for undergraduate and graduate students and liberal arts courses, non-degree diploma programs for professional artists, and musical training for pre-college students. Juilliard has a single campus at the Lincoln Center for Performing Arts, comprising numerous studio rooms, performance halls, a library with special collections, and a dormitory. It has one of the lowest acceptance rates of schools in the United States. With a total enrollment of about 950 students, Juilliard has several student and faculty ensembles that perform throughout the year, most notably the Juilliard String Quartet.
