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. Visiting Mountain Lakes?

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. For dinner in the area, see our guide to the best restaurants in Kinnelon.

All 39 Morris County Towns: Population and Size

Here is every municipality in Morris County with its official form of government, its population at the 2020 Census, and its land area, from the U.S. Census Bureau and the Morris County Office of Planning and Preservation.

Why Are There Two Boontons, Chesters, Mendhams, and Rockaways?

It is one of the most confusing things about Morris County for newcomers. Boonton, Chester, Mendham, and Rockaway each have two separate municipalities with the same name: a smaller, denser downtown (a town or borough) and a larger, more spread-out township around it. They share a name and history, but each has its own mayor, council, and budget. Morristown and Morris Township work the same way: the town of Morristown is the compact downtown around the Green, and Morris Township surrounds it on almost every side. When someone says they live in Chester or Rockaway, it is worth asking which one.
