city, Warren county, east-central New York, U.S., on the Hudson River, 45 miles (72 km) north of Albany. Part of the Queensbury Patent (1759; now Queensbury town 【township】), it was settled in the 1760s by Quakers (Friends, Society of) as Wing's Falls (for Abraham Wing, leader of the settlers) and was renamed (1788) for Colonel Johannes Glen, who built mills there. Lumbering, paper, and clothing industries developed based on waterpower generated by the 60-foot (18-metre) falls. James Fenimore Cooper (Cooper, James Fenimore) described the falls, which the Mohawk Indians called Chepontuo (“Difficult Place to Get Around”), in a graphic scene from his novel The Last of the Mohicans; and Cooper's Cave, where the character Hawkeye took refuge with his party, is beneath the bridge that links the city with South Glens Falls.

Modern industries produce paper, medical devices, textiles, capacitors, and brass fittings. The Hyde Collection, a community trust collection of art founded in 1952, includes works by Picasso (Picasso, Pablo), Rembrandt (Rembrandt van Rijn), and El Greco (Greco, El). Adirondack Community College was founded at Glens Falls in 1961. A large amusement park and the West Mountain Ski Resort are nearby. Inc. village, 1839; city, 1908. Pop.
