About Us

Founded in 1958 by a group of devoted parents, Harbor Country Day School is a nonprofit, independent private school for preschool through eighth grade in Suffolk County, New York.   We are located in the Township of Smithtown nestled in the quiet Village of Head of the Harbor along Long Island’s north shore about 90-minutes from New York City.

Harbor students approach learning with a fearlessness that only comes from knowing that they will be safe and accepted regardless of whether they succeed or fail. They embrace the hard work that comes with a rigorous curriculum like Harbor’s because they are taught from the day they enter the school how to work with purpose, and how to make it fun.

Public speaking, community service, athletics, cross-divisional mentoring programs, upper school leadership retreats, social-emotional learning programs --all of these opportunities, and so many more, help children realize their full potential as individuals and as leaders so that when they leave Harbor, they are fully prepared to master the challenges of secondary school, college, and life beyond.

We are chartered by the New York State Board of Regents and is accredited by, and a member of, the New York State Association of Independent Schools (NYSAIS).  It is a non-sectarian, non-profit organization under section 501(c)(3) of the IRS Code governed by a self-perpetuation board of trustees.
