Garrison is a hamlet in Putnam CountyNew YorkUnited States. It is part of the town of Philipstown, on the east side of the Hudson River, across from the United States Military Academy at West Point. The Garrison Metro-North Railroad station serves the town and is a 70 minute train ride on the Metro-North Hudson Line to Grand Central Terminal.

Garrison is home of the Garrison Union Free School; it is a K–8 school. Graduating students have the choice of going to Haldane in Cold Spring or across the river to O'Neill in Highland Falls for high school.

Half of Garrison is either publicly owned property or set aside as open space. One of the few areas of high density is Garrison Landing, the hamlet’s hub near the Metro-North Railroad station, which used to be a boat landing and loading point for farmers. It is home to historical structures, as well as the Garrison Art Center and the 80-seat Depot Theater, formerly a train station.

Spectacular views of the river can be found most everywhere, but a favorite is from the first tee at the Garrison Golf Club and Inn on Route 9, above a point where the water snakes around the shoreline. On the opposite shore, the view of Garrison from West Point includes a vista of homes and swimming pools tucked into mountain ledges. Most of the houses — new and older colonials and Victorians, some with horse paddocks — sit back on dirt roads that weave through rocky, wooded terrain.

According to Don H. MacDonald, the town’s historian, the land that is now Philipstown, of which Garrison is a part, was bought from the Wappingers Confederation of Indians in 1691 by Lambert Dorlandt and Jan Sybrant, both Dutch. Six years later, they sold the property to Adolph Philipse, whose descendants lost the land because they sided with the British in the Revolution.
