Valley Cottage is a hamlet and census-designated place in the town of Clarkstown, New York, United States.

[4] According to the United States Census Bureau, the CDP has a total area of 4.4 square miles (11 km2), all land.

The first known resident of Valley Cottage was John Ryder, who owned a large farm which comprised all or most of the area's school district.

According to George H. Burke's book Rockland County during the American Revolution, 1776–1781, Valley Cottage was once known as "Storm's Corner".

In 1876, just before the opening of the West Shore Railroad station, the residents assembled at the school room agreed on the name "Valley Cottage", referring to the house nearest the station "that cottage in the valley".

Another version has it that the name of the hamlet came about because of a famous trotting horse named "Cottage Maid", owned by Ed Green who owned the land where the station, the Marcus store and other buildings stood.

Valley Cottage is located along CSX Transportation's River Line, with between 20 and 55 freight trains passing through the hamlet daily.
