Matawan is a borough in Monmouth County, New Jersey, United States. As of the 2010 United States Census, the borough population was 8,810. The name "Matawan" comes from a Native American Lenape word.
Matawan is part of the Bayshore Regional Strategic Plan, an effort by nine municipalities in northern Monmouth County to reinvigorate the area's economy by emphasizing the traditional downtowns, dense residential neighborhoods, maritime history, and the natural beauty of the Raritan Bayshore coastline.
Matawan was formed as a borough on June 28, 1895, from portions of Matawan Township (now Aberdeen Township), based on the results of a referendum held that day. Matawan expanded with portions of Matawan Township in 1931 and 1933, and from Madison Township (now Old Bridge Township) in 1939.
