Garrison Union Free School

Garrison Union Free School, also referred to as just Garrison School, educates students from kindergarten through eighth grade in the eponymous school district, which covers the hamlet of Garrison and nearby areas of the towns of Philipstown and Putnam Valley in Putnam County, New York, United States. It is located on NY 9D near the center of the hamlet, right across from St. Philip's Church in the Highlands, where it was originally located when established in 1793.

Graduating students who continue their education in public schools have the choice of doing so either at Haldane High School, to the north in Cold Spring; or James I. O'Neill High School across the Hudson River in Highland Falls. The district pays tuition for both.
