Long Hill Township is a township in Morris County, located in north-central New Jersey between the metropolitan suburbs and the Highlands. The township follows the Passaic River valley near the Great Swamp, bringing together several established communities, rail stations, and wooded residential areas. Morris County combines historic downtowns and major employment centers with lakes, wooded hills, reservoirs, parks, and lower-density western townships. Corporate offices, healthcare institutions, research and technology employers, retail districts, residential neighborhoods, and recreation areas shape the county’s economy and daily life. Interstates 80 and 287, Routes 10, 24, and 46, and regional rail service connect county communities with Newark, New York City, and western New Jersey. Long Hill Township maintains its own municipal identity while its neighborhoods and local destinations remain closely connected with the wider Morris area.
