Raritan Township, Administrative division in Hunterdon County, New Jersey, United States.
Raritan Township is an administrative division in Hunterdon County, New Jersey, covering a substantial land area divided between valley regions. The South Branch Raritan River flows through the township, shaping much of its natural geography and drainage patterns.
The township was established in 1838, carved out from portions of Amwell Township in the region. In 1910, Flemington incorporated as an independent municipality, yet it remained surrounded by Raritan Township's boundaries.
The township takes its name from the Raritan people, a branch of the Lenape nation who lived in this region before European arrival. This Native American heritage remains woven into the local landscape and community identity.
This is primarily a residential and agricultural area without a central commercial hub, so visitors should plan to explore its dispersed neighborhoods and natural features. Spring and fall offer the most pleasant conditions for touring the township's landscapes and rural character.
Raritan Township completely surrounds the city of Flemington in a ring-like formation known as a doughnut town, one of only 21 such municipal configurations in New Jersey. This unusual geographic and administrative arrangement means that Flemington sits entirely within the township's boundaries while maintaining separate governance.
