Delaware Township is a Township in Hunterdon County, New Jersey, United States. Part of the township is on the Hunterdon Plateau, while the souther portions are in the Amwell Valley. As of the United States 2000 Census, the township population was 4,478. The historic community of Sergeantsville is located within Delaware Township, as is the unincorporated area of Raven Rock. Other villages are Croton, Locktown, Sand Brook, and Rosemont.Delaware was incorporated as a township by an Act of the New Jersey Legislature on April 2, 1838, from a portion of a larger municipality then known as Amwell Township (now defunct). Historian and cartographer John P. Snyder has erroneously stated that a referendum was held on that date, but there was in fact no referendum and the people of Amwell knew nothing about the division until after the Legislature passed the bill.A portion of the township was taken to form Stockton borough (April 14, 1898).
