Yantacaw Brook Park is a town operated park located in Montclair, New Jersey, United States. The park takes up 11.5 acres (47,000 m²) of land. It has a small pond and the stream that feeds it and is surrounded by trees and small sloped hills with benches, with paths going through. The stream that empties into the pond and then continues at the other end of the pond is called the Yantacaw Brook. The Brook then continues into Third River in Bloomfield, New Jersey and then into Belleville, New Jersey and Nutley, New Jersey, where it enters the Passaic River. Yantacaw Brook Park should not be confused with Nutley's larger Yanticaw Park through which the same water body flows.
