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. Eleazar Lord, author, educator, deacon of the First Protestant Dutch Church 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.
Sparkill Creek cuts through the north end of the Hudson Palisades, providing easy access to the fertile valley of the unnavigable upper Hackensack River. "Tappan Landing," "Tappan Slote", or "Taulman Landing," as the little port was called, thus became the original port for southern Orange County. The valley in the Palisades created by the creek also provided a way for the Erie Railroad to easily reach the Hudson, and the railroad built a long pier in 1839 as its principal terminal. The pier and the nearby mountains suggested a new name for the community, which was incorporated as a village in 1850. The pier was a major embarkation point for World War II troops traveling from Camp Shanks to the European Theater.
