Little Falls is a township in southeastern Passaic County along the Passaic River, between Woodland Park, Totowa, Wayne, Cedar Grove, and Montclair. The municipality includes the communities of Little Falls, Great Notch, and Singac, each with a different residential and commercial pattern. U.S. Route 46, Route 23, and nearby Interstate 80 provide regional highway access, while NJ Transit stations on the Montclair-Boonton Line connect the township with Newark, Hoboken, and New York connections. Residential neighborhoods, apartment complexes, schools, parks, small businesses, and light industrial areas are distributed across the township. Montclair State University lies along the southern border and contributes to activity near Great Notch. River valleys, floodplains, and wooded slopes shape the local terrain. Little Falls' location at the edge of the denser Essex County suburbs and the Passaic County highway network gives it a varied and well-connected suburban identity.
