Long Hill Township is a township in Morris County, New Jersey, United States. As of the 2010 United States Census, the township's population was 8,702,[9][10][11] reflecting a decline of 75 (-0.9%) from the 8,777 counted in the 2000 Census, which had in turn increased by 951 (+12.2%) from the 7,826 counted in the 1990 Census.[22]

Long Hill Township was incorporated as Passaic Township on March 23, 1866. On September 1, 1922, part of what was then Passaic Township was taken to form Harding Township.[23][24] On November 3, 1992, by a 1,901-1,821 margin, the voters elected to change the name of the municipality to Long Hill Township, a change largely driven by the desire to avoid confusion with the City of Passaic, some 22 miles (35 km) away.[25][26]

​

According to the United States Census Bureau, the township had a total area of 12.136 square miles (31.432 km2), including 11.851 square miles (30.693 km2) of land and 0.285 square miles (0.739 km2) of water (2.35%).[1][2]

Unincorporated communities, localities and place names located partially or completely within the township include Gillette, Millington, and Stirling, and the hamlet of Meyersville. Homestead Park is a subdivision that was first developed in the 1920s.[27]

The township is located in the most southern part of Morris County. It is bounded by the Passaic River on the south and west and by the Great Swamp National Wildlife Refuge on the north. It borders both Union and Somerset counties.

The Great Swamp National Wildlife Refuge covers 7,455 acres (3,017 ha) of land overseen by the United States Fish and Wildlife Service and includes portions east of New Vernon Road that is unmanaged and accessible by visitors, while areas west of New Vernon Road are managed intensively and are not available to the public.[28]

​

As of the 2014-15 school year, the district and its three schools had an enrollment of 1,314 students and 71.3 classroom teachers (on an FTE basis), for a student–teacher ratio of 18.4:1.[82] Schools in the district (with 2014-15 enrollment data from the National Center for Education Statistics[83]) are Gillette School[84] (184 students; in grades PreK-1), Millington School[85] (332; 2-5) and Central Middle School[86] (314; 6-8).[87]

Long Hill Township's high school students in public school for ninth through twelfth grades attend Watchung Hills Regional High School in Warren Township. Students from Long Hill Township and from the neighboring communities of Green Brook Township, Warren Township and Watchung (in Somerset County) attend the school.[88][89] As of the 2014-15 school year, the high school had an enrollment of 1,286 students and 94.6 classroom teachers (on an FTE basis), for a student–teacher ratio of 13.6:1.[90]

St. Vincent de Paul School was a Catholic school in Stirling that operated under the auspices of the Roman Catholic Diocese of Paterson. The school closed in June 2016 in the wake of declining enrollment and financial challenges.[91] The school was recognized with the Blue Ribbon School Award of Excellence in 2012.[92]
