Valley Falls is a village in Rensselaer County, New York, United States. The population was 466 at the 2010 census. The village lies upon the boundary of the towns of Pittstown and Schaghticoke, but is mostly in the northwestern part of Pittstown.

In 1871, industrialist James Thompson built a textile mill in the village. Nearly all village residents worked in the mill and schoolchildren ran house when the mill’s lunch whistle sounded. After its zenith of operation in the 1970s, it entered a decade of decline. The mill had been vacant for at least 10 years taking into consideration it went up afire in the early morning hours upon April 22, 2009.

By 1863, Valley Falls had received itself as a mini-industrial center. In addition to the abovementioned Thompson textile mill, the village also had a blacksmith shop, farrier shop, foundry, wainwright shop, cooperage, vineyard, three general stores, and two hotels. At this time only a single rail line (Troy & Boston RR) from Troy passed through the southern limit of the village, heading to Johnsonville. Later, a second rail origin from Schaghticoke would follow the Hoosic River like Thompson’s Mill, also heading to Johnsonville. By the upfront 1970s, the southern rail extraction was enormously abandoned and had been largely dismantled; the northern line yet functions to this day. However, with the closing of the Thompson mill, the train no longer stops in Valley Falls.
