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 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.

Sparkill Creek cuts through the north end of the Hudson Palisades, providing easy access to the fertile valley of the unnavigable upper Hackensack River.

[4] Late in the 20th century, Piermont became a modest tourist attraction for day-trippers from New York City, particularly those bicycling on Bike Route 9.

In 2024 the village government led by Bruce Tucker became embroiled in controversy around a proposed three-story residential building in downtown.

The legality of the village's Board of Trustees' amendment to its zoning code to facilitate the proposed development was openly challenged by the Rockland County Planning Department.

Village residents also raised concerns about increased traffic, parking issues, and the site having previously served as a gas station with underground storage tanks.

[8] [9] In response to a lawsuit filed by village residents, on October 11, 2024 Rockland County Supreme Court Justice Hal Greenwald declared the law which created the Piermont Central Business Multi-Use (CBM) Zoning District “null, void and jurisdictionally invalid.” The ruling was based on the failure, under Rockland County General Municipal Law, for the Village of Piermont to have referred the law creating the new zoning district to the County Planning Department for final approval.

[10] In November 2024 the concrete end of the historical Piermont Pier was closed off as it was deemed to be structurally deficient and at risk of imminent collapse.

Piermont Railroad Station, located on Ash Street, is a Victorian Stick style structure built in 1873 which served as Piermont's stop for the former Erie Railroad Northern Branch north–south line, which went from Nyack, New York, to Jersey City, New Jersey.

The exterior of the building was renovated to its original architecture and French gray, light-green and oxide-red color scheme in 2006 by the Piermont Historical Society.

Allan King Sloan, the great-great-grandson of the company's founder, provided some of the information that is on the historical marker nearby and attended the dedication ceremony on August 7, 2009.
