The Knickerbocker Ice Company was an ice company based in New York State during the 19th century.

The ice trade, also known as the frozen water trade, was a 19th-century and early 20th-century industry, centering on the east coast of the United States and Norway, involving the large-scale harvesting, transport and sale of natural ice, and later the making and sale of artificial ice, for domestic consumption and commercial purposes. Ice was cut from the surface of ponds and streams, then stored in ice houses, before being sent on by ship, barge or railroad to its final destination around the world.
