How Many Towns Are in Morris County?
Morris County has 39 municipalities. They are a mix of towns, townships, and boroughs, each with its own local government, but all part of one county that stretches from the Chatham and Madison area in the southeast to Mount Olive and the Highlands in the west.
Morristown and the Central Towns
The heart of the county sits around the county seat. This group includes Morristown, Morris Township, Morris Plains, Hanover Township, East Hanover, Florham Park, and Harding Township. Morristown anchors the region with its historic Green, Revolutionary War sites, restaurants, and train access, and the surrounding towns blend corporate campuses, parks, and established neighborhoods.
Madison and the Chathams
Just to the southeast are Madison, Chatham Borough, and Chatham Township. Known for walkable downtowns, strong schools, and easy commutes, these three are among the most sought-after addresses in the county.
The Route 10 and Route 46 Corridor
The busy commercial spine of the county runs through Parsippany-Troy Hills, Denville, Randolph, Rockaway Borough, Rockaway Township, Dover, Victory Gardens, Wharton, and Mine Hill. Parsippany-Troy Hills is the county’s largest town by population, Denville is known as the Hub with its lakeside downtown, and Dover brings a lively arts and dining scene. Victory Gardens is the county’s smallest municipality.
The Lake and Highlands Towns
Out west and north you will find Mount Arlington, Roxbury, Mount Olive, Netcong, Jefferson Township, and Mountain Lakes. Several of these border Lake Hopatcong, the largest freshwater lake in New Jersey, and the area is a summer draw for boating, beaches, and hiking.
The Mendhams, Chesters, and the West
The county’s rolling farm country is home to Mendham Borough, Mendham Township, Chester Borough, Chester Township, Washington Township, and Long Hill Township. Chester’s historic Main Street, the farms around Long Valley in Washington Township, and open space define this quieter, more rural corner.
Boonton, Montville, and the Northeast
The northeastern edge of the county includes Boonton Town, Boonton Township, Montville, Pequannock, Lincoln Park, Kinnelon, Butler, and Riverdale. This group mixes historic downtowns like Boonton with wooded, lake-dotted communities such as Kinnelon.
