Hewitt is an unincorporated community in the northern portion of West Milford Township, Passaic County. It lies within the New Jersey Highlands near Greenwood Lake and the New York State line, an area characterized by wooded hills, lake neighborhoods, wetlands, and winding local roads. The Hewitt name is commonly used for postal addresses serving several nearby residential communities rather than a separately incorporated municipality. Local businesses and community facilities are dispersed along the roads connecting Greenwood Lake, Upper Greenwood Lake, and other sections of West Milford. The surrounding landscape is markedly different from the denser eastern portion of Passaic County, with larger parcels, seasonal views, and extensive natural areas. Residents travel south toward Route 23 and central West Milford for broader shopping and municipal services, while roads north and east connect to Warwick, Ringwood, and neighboring lake communities. Hewitt’s identity is closely tied to the township’s outdoor recreation, lake culture, and Highlands setting.
