Convent of the Sacred Heart is an independent Catholic all-girls' school in the Manhattan, New York City. Teaching from pre-kindergarten through twelfth grade, it is located on the Upper East Side at East 91st Street and Fifth Avenue.
The school is housed in the former Otto H. Kahn House and James A. Burden House, both of which are New York City-Designated Landmarks, and are listed on the National Register of Historic Places.
Founded in 1881 by the Society of the Sacred Heart, a Catholic women's religious congregation established in France in 1800, the school is one of New York City's oldest private schools for girls.
The school was originally housed in a Manhattan brownstone on Madison Avenue at East 54th Street. By the 1930s, the school had outgrown its Madison Avenue space and moved into the Otto H. Kahn House. In 1940, the society acquired the James A. Burden House next door.
In addition to being a member of the Society of the Sacred Heart and a part of the global Network of Sacred Heart Schools, a worldwide network of over 150 schools committed to the mission of a Sacred Heart education, the school is accredited by the New York State Association of Independent Schools and is a member of the National Association of Independent Schools.
It is operated independently as part of the Network of Sacred Heart Schools. The school is also associated with the New York Interschool Association.
The school is also a member of the Independent Schools Association of Greater New York, the National Coalition of Girls’ Schools, the European Council of International Schools, the International Schools Association and the Network of Sacred Heart Schools in the United States.
The school is located in two historic mansions in the Carnegie Hill Historic District on the Upper East Side of Manhattan, at 1 East 91st Street and 7 East 91st Street, next to Central Park/Fifth Avenue and across the street from the Cooper-Hewitt Museum.
In September 2008, the school purchased a facility located at 406 East 91st Street and created a new sports center. As of September 2014, the athletic center was open.
The school participates in eleven interscholastic sports disciplines.
There is a separate athletic building at 406 91st Street near First Avenue.
