Stillwater Township is a township located in Sussex County, in the U.S. state of New Jersey. Situated in the Kittatinny Valley, Stillwater is a rural farming community with a long history of dairy farming. As of the 2020 United States census, the township's population was 4,004, a decrease of 95 (−2.3%) from the 2010 census count of 4,099, which in turn reflected a decrease of 168 (−3.9%) from the 4,267 counted in the 2000 census.
Stillwater was settled in the eighteenth century by Palatine German immigrants who entered through the port of Philadelphia. In 1741, Casper Shafer, John George Wintermute (Windemuth), and their father-in-law Johan Peter Bernhardt settled along the Paulins Kill. For the next 50 years, the village of Stillwater was essentially German, centered on a union church shared by Lutheran and German Reformed (Calvinist) congregations. The German population assimilated by the early nineteenth century, but evidence of their settlement remains in the architecture of the grist mills, lime kilns, and stone houses located throughout the valley. Stillwater was incorporated as a township by an act of the New Jersey Legislature on December 27, 1824, from portions of Hardwick Township when Sussex County was divided in half by the legislature a few weeks earlier to create Warren County. Portions of the township were taken to form Fredon Township on February 24, 1904.
In 2008, New Jersey Monthly magazine ranked Stillwater Township as its 40th best place to live in its annual rankings of the "Best Places To Live" in New Jersey.
History
The township was created on December 27, 1824, by an act passed by the New Jersey Legislature.
A prominent structure in the area's history is the Shafer Grist Mill. Originally built by Casper Shafer in 1741, it was moved approximately a half mile to its present location in 1764. It was rebuilt in 1844 and powered by water from the Paulins Kill. Casper's son, Nathan Armstrong Shafer lived in Whitehall Manor, which he built near what is now the center of the village. The gristmill operated commercially until 1955, making it one of the oldest, continuously operating, water-powered gristmills in the State of New Jersey. Aline Murray Kilmer, the widow of poet Joyce Kilmer, lived the last decade of her life at Whitehall, dying there on October 1, 1941.
In the early 1900s, Swartswood Lake became a major resort. Weekenders took the train into nearby Blairstown through the 1940s to stay at such places as the North Shore Inn, The Casino, and The Dove Island Inn (now a private home). Later, summer cabins became popular with Brooklyn weekenders.
The Stillwater creamery was built in 1910. Borden, Inc. later took control of the creamery.
In the 1920s, the Paulins Kill was dammed to create Paulins Kill Lake and many summer residences sprang up. These summer cottages have grown into what is now a year-round community.
The Presbyterian Church is the most prominent feature in Stillwater village. Opposite the church is the former Academy, an old schoolhouse that is now home of the Historical Society of Stillwater Township. Stillwater was, and still is, primarily agricultural. The area is dotted with lime kilns, which used to burn lime to enrich the soil, but are now obsolete, becoming lost to history and the overgrowth of vegetation. An intact kiln still exists on Millbrook Road, a little more than two miles (3 km) from Stillwater village.
Roughly one-third of Stillwater Township's area was ceded to create Fredon Township in 1904.

Stillwater is a small one-street village in the area that was first settled by Johan Peter Bernhardt and his two sons-in-law, John George Wintermute and Casper Shafer. At the western terminus of end of Main Street where it meets County Route 521, the First Presbyterian Church of Stillwater is the dominant feature. As Main Street travels east, the Garris's General Store (1876), "Whitehall" (built in 1785 by Abraham Shafer), Casper Shafer's stonehouse (c. 1741), crossing the Paulins Kill near Shafer's grist mill (1764, 1844) and miller's house. An 1820 hostelry, the Stillwater Inn, recently was destroyed by fire. One half-mile (800 m) south of the Presbyterian church, is John George Wintermute's stonehouse (1755), his son Peter's stonehouse (1791). Located adjacent is Stillwater Cemetery—the site of the original Lutheran-Calvinist union church (1771–1838), the graves of the towns earliest settlers, and many eighteenth century ethnic German gravestones.
Geology
Flanked to the west by Kittatinny Mountain, the Stillwater Township is located within the Ridge and Valley Physiographic Province, and the entire township is within the Kittatinny Valley a region of rolling hills and flat valley floors that is a section of the larger Great Appalachian Valley running 700 miles (1,100 km) from eastern Canada to northern Alabama. Elevations in this valley range from 400 to 1,000 feet (120–300 m). According to Snell, "The surface of the country is generally uneven and hilly, and on the west exceedingly rugged and mountainous. Ponds and watercourses abound. Of the latter, the most important is the Paulinskill, a millstream of considerable consequence." All of Stillwater Township is located in the Paulins Kill watershed which flows southwest through Sussex and Warren counties before joining the Delaware River near Columbia, New Jersey. The valley floor is part of the Ordovician Martinsburg Formation (shale and slate) which make up most of the valley—and the Jacksonburg Formation (mostly limestone).
Climate
Stillwater Township is located in Northwestern New Jersey which has a humid continental climate (microthermal)—a cooler climate due to its higher elevations.

The Township Committee is comprised of five members, who are elected directly by the voters at-large in partisan elections to serve three-year terms of office on a staggered basis, with either one or two seats coming up for election each year as part of the November general election in a three-year cycle.
