Mauricetown (pronounced "Morristown"[6]) is a census-designated place[7] and unincorporated community that is part of Commercial Township in Cumberland County, in the U.S. state of New Jersey.

[1][8][9] The construction of County Route 649, a modern bypass road, has significantly reduced traffic through the community, resulting in a quiet, tranquil atmosphere with minimal automobile congestion.

The settlement is built on high ground overlooking the Maurice River, which supported Mauricetown's economic boom during the 19th century, when the community was active in coastal trade and shipbuilding.

Mauricetown proper is surrounded on three sides by the grassy salt marshes, tidal flats, small creeks, and the Maurice River, and is located about 6 miles (9.7 km) upriver from the Delaware Bay.

The Caesar Hoskins Log Cabin, one of the earliest buildings in Mauricetown and all of southern New Jersey, is listed on the National Register of Historic Places.
