The Kipsey is a lesser-known river cryptid associated with the Hudson River near Poughkeepsie, with reports describing a large, serpentine or eel-like creature surfacing briefly before submerging. Sightings from the 19th and early 20th centuries mention massive coils, dark scaled skin, and sudden disturbances in the water, often observed by boaters and riverside workers. More recent accounts from the late 20th century reference unusual wakes and long-bodied shapes captured fleetingly on amateur video, though no definitive footage has been verified.
