Piermont is a village in Rockland County, New York, United States. Piermont is in the town of Orangetown, located north of the hamlet of Palisades; east of Sparkill and south of Grand View-on-Hudson, on the west bank of the Hudson River. The population was 2,607 at the 2000 census. The village's name, in earlier years known as Tappan Landing, was given by Dr. Lord Eleazar, author, educator and first president of the Erie Railroad. It was derived by combining a local natural feature – Tallman Mountain – and the most prominent man-made feature of the village – the long Erie Railroad pier.
