The Pascack Valley is the name for a region of New Jersey, United States, contained within Bergen County. It is named for the Pascack Brook. The region consists of eight municipalities: Montvale, Park Ridge, Woodcliff Lake, Hillsdale, Westwood, River Vale, Washington Township, and Emerson.[1] The neighboring municipalities of Old Tappan and Oradell are sometimes considered to be part of the Pascack Valley, as both boroughs are included in the Greater Pascack Valley Chamber of Commerce.
