Plainfield is a village in Will and Kendall counties, Illinois, United States. The population was 44,762 at the 2020 census.

The village includes land in Will County's Plainfield and Wheatland townships, as well as Na-Au-Say and Oswego townships in Kendall County. With the growth in the Chicago suburbs in the 1990s and 2000s, the village has seen a population increase, from 4,500 in 1990 to 28,000 in 2000 to nearly 45,000 in 2016. It is between the cities of Naperville and Joliet.

The village has established a community Preservation Commission and historic preservation ordinance. It is the home of the Lake Renwick Preserve, a county forest preserve used for birdwatching and other activities. Located south of Village Hall is Settlers' Park, which includes a lake, war monument, open space, and more. The park presents outdoor concerts to the public in the summer.^[3]

The area was called "Walkers' Grove" until it was platted as "Plainfield" in 1841. It was originally settled by a large community of Potawatomi people, and the land was later bequeathed to the United States as part of the Treaty of St. Louis (1816) with the Council of the Three Fires. Indian Boundary Road aligns with the western border of the tract of land originally ceded.

The earliest Europeans in the area were French fur traders. The first European-American settler in the area was James Walker, who with his father-in-law, Methodist minister Jessie Walker, traveled here in 1826 where he established a small mission for the Potawatomi people. James Walker, Jesse Walker's son-in-law, traveled with him and became the first European-American to claim land in the area in 1828.^[4]

In 1828, James Walker, in the company of several men, erected a sawmill around which the settlement of Walkers' Grove developed.

Plainfield is identified as the oldest community in Will County because the earliest settlement of Walkers' Grove was established on the banks of the DuPage River by 1828. However, the actual village of Plainfield was platted immediately north of Walkers' Grove in 1834 by Chester Ingersoll. The separate community of East Plainfield was platted in June 1836 by James Mathers, who began selling lots in July 1836. He also constructed a gristmill and a mill race west of Water Street, which would later become Plainfield-Naperville Road. Ingersoll's "Planefield" (Plainfield) which comprised lots in Section 16, along with Mather's East Plainfield lots in Section 10 and Levi Arnold's plat of Section 9, all became joined to create the present-day village after the death of Levi Arnolds in 1845.

Walkers' Grove flourished because of the DuPage River and established routes to Fort Dearborn in Chicago, as well as to Ottawa to the west. Reuben Flagg hauled lumber from Walker's mill to Chicago in order to erect the first two frame structures in the city (the P.F.W. Peck House and the George Dole Forwarding House). Chicago also depended upon the settlement for mail and supplies.

The community's early prosperity was stunted when the Illinois and Michigan Canal opened in 1848, because the village was not located along the canal. Located within the village are numerous Greek Revival, Upright and Wing cottages,^{[5][clarification needed]} a school built in 1847, and a number of early-19th-century homes. Plainfield currently has three buildings listed on the National Register of Historic Places: Plainfield Halfway House, Flanders House, and a 1928 Standard Oil gas station.^[6]

Plainfield abolitionists offered food and shelter to runaway slaves following the Underground Railroad.^[7]

North Central College was founded in the village in 1861 as Plainfield College.

The Plainfield Public Library District was founded in the village in 1925 as the Nimmons Village of Plainfield Free Public Library.

Plainfield is the birthplace of Eddie Gardner, one of the pilots credited with establishing the transcontinental air mail routes for the United States Postal Service. The earliest architects associated with buildings in Plainfield are J.E. Minott of Aurora; G. Julian Barnes & John H. Barnes of Joliet; and Herbert Cowell of Joliet and Plainfield.^[8]

Certain older parts of Plainfield once suffered from extreme traffic congestion. Before Interstate 55 was built just east of the village in the late 1950s, U.S. Route 30 (the Lincoln Highway) and U.S. Route 66 (sometimes referred to as "The Mother Road") merged into one street for three blocks in the center of town on what is now Illinois Route 59. The merge was between Plainfield/Joliet Road on the south to Lockport Street on the north, but continues to be an area of heavy traffic congestion even outside heavy commuting periods.^{[original research?]} At one time, the two longest paved highways in the world (Lincoln Highway and U.S. Route 66) crossed within Plainfield. The highways only crossed each other twice and both locations are in Will County. The other location is in neighboring Joliet.

On August 28, 1990, an F5 tornado ran its course through Plainfield. The "Plainfield Tornado" killed 29 people, 24 of whom were killed instantly, and 350 were injured. More than 1,100 homes were damaged and destroyed. The tornado made it across more than 16 miles (26 km) in only 8 minutes. It destroyed the only Plainfield high school at the time, now called Plainfield Central High School.^[9] A population boom started to take place at the end of the 20th century after the tornado, with a large number of new home subdivisions. Before this, Plainfield was primarily an agricultural town.

Plainfield is located in northwestern Will County. The village limits extend west into the eastern part of Kendall County. Plainfield is bordered to the north by the city of Naperville, to the northeast by the village of Bolingbrook, to the east by the village of Romeoville, and to the south by the city of Joliet. Farmland in Kendall County is to the west.

Interstate 55 runs along the eastern edge of the village, with access from two exits. I-55 leads northeast 34 miles (55 km) to the center of Chicago and southwest 100 miles (160 km) to Bloomington. U.S. Route 30 passes through the center of Plainfield, leading northwest 13 miles (21 km) to Montgomery and southeast 9 miles (14 km) to Joliet. Illinois Route 126 crosses US-30 in the center of Plainfield, leading northeast 2.5 miles (4.0 km) to I-55 and west 14 miles (23 km) to Yorkville. Illinois Route 59 runs through the center of Plainfield with US-30 but leads north 9 miles (14 km) to the west side of Naperville and south 6 miles (10 km) to Shorewood.

According to the 2010 census, Plainfield has a total area of 24.199 square miles (62.68 km²), of which 23.22 square miles (60.14 km²) (or 95.95%) is land and 0.979 square miles (2.54 km²) (or 4.05%) is water.^[10] The DuPage River flows through the village center, running south towards the Des Plaines River in the Illinois River watershed.

Like its namesake, Plainfield's topography is generally flat. Thousands of years ago, land in greater Plainfield used to be part of the bed of proglacial Lake Wauponsee. However, the lake did not hold up long, and eventually drained into the Illinois River valley.^[11] The lake left behind a very flat landscape. Much of downtown Plainfield has an elevation of around 600–625 feet (183–191 m) above sea level, with some areas in the western and northwestern portions of the village's outskirts exceeding 700 feet (210 m). This rise in elevation was created by terminal moraines that were formed during the Wisconsin Episode of the last ice age's last glacial period that has been recorded.

As of the census^[16] of 2010, there were 39,581 people, 11,920 households, and 10,155 families residing in the village. The population density was 1,621.5 inhabitants per square mile (626.1/km²). There were 12,532 housing units at an average density of 513.4 per square mile (198.2/km²). The racial makeup of the village was 81.72% White, 5.56% African American, 0.22% Native American, 7.62% Asian, 0.04% Pacific Islander, 2.6% from other races, and 2.22% from two or more races. Hispanic or Latino of any race were 10.73% of the population.

There were 11,920 households, out of which 55.4% had children under the age of 18 living with them, 74.2% were married couples living together, 7.9% had a female householder with no husband present, and 14.8% were non-families. 11.5% of all households were made up of individuals, and 2.9% had someone living alone who was 65 years of age or older. The average household size was 3.31 and the average family size was 3.62.

In the village, the population was spread out, with 35.2% under the age of 18, 6% from 18 to 24, 31.8% from 25 to 44, 21.7% from 45 to 64, and 5.3% who were 65 years of age or older. The median age was 33.8 years. For every 100 females, there were 98.4 males. For every 100 females age 18 and over, there were 95 males.^[17]

According to a 2014 estimate by the U.S. Census, the median income for a household in the village was $111,536 (~$141,409 in 2023).^[18] About 1.0% of families and 1.8% of the population were below the poverty line, including 2.2% of those under age 18 and 2.3% of those age 65 or over.

In the mid 1800's, the business district of Plainfield consisted of wood-framed buildings of all shapes and sizes, yet between 1-2 stories high, and commonly had projecting awnings of wood and metal, along with either false fronted, horizontal wood cornices or large display windows.^[19] There were wood plank sidewalks that were elevated 2ft above the dirt roads on a limestone foundation.^[19] The last wood-framed building constructed on Lockport St. was in 1869, and the first masonry buildings constructed along Lockport St. were in 1865, and the post 1870 masonry buildings introduced a new commercial look where common design themes began to integrate the buildings together; including: identical floor and roof lines, cast iron storefronts with larger windows, operable canvas awnings, stamped metal cornices, etc..^[19]

The early church buildings of Plainfield were wood-framed and imposed Greek Revival and Gothic Revival edifices along the dirt roads.^[19] In the 1850's, four different congregations built churches along Lockport street, including the Methodists, Congregationalists, the Baptists, and the Evangelicals.^[19]

In 1836 the Methodists built a wood-framed church (located on present-day Lockport street), and in 1868 they built another church much larger and of limestone (located on present-day Illinois street in downtown Plainfield).^[19][20] The original church built in 1836 was later converted into a business on the first floor and a social hall on the second floor.^[19]

In 1850 the Congregational Church (located at present-day Lockport and Illinois streets) was built and cost $2,200.^[20] The east wing of the church was added in 1907.^[20]

In 1836 the Baptist church erected their first church, sized at 26ft by 36ft, and cost of $2,500.^[20] This church was later turned into a blacksmith shop in 1857 following the construction of a new church that costed $4,500-$5,000, and burned down in 1914, then rebuilt on the same site again (located at present-day Division and Lockport streets).^[20]

Major highways in Plainfield include:

The Pace bus system expanded two routes (755 and 855) to Plainfield beginning May 6, 2013. Both routes are "bi-directional, weekday rush hour service"^[21] from the Plainfield Village Center to Downtown Chicago. One route terminates in the Illinois Medical District and the other in Chicago's East Loop.^[22]

Plainfield Community Consolidated School District 202 serves portions of Plainfield, Joliet, Crest Hill, Bolingbrook, Romeoville, and Plainfield Township in unincorporated parts of Will County.

Peak enrollment in the district took place in 2010–2011 at 29,254 students. The enrollment has been steadily declining since that time, and is currently declining at several hundred students per year. Current enrollment is 24,737 for the 2022-2023 school year.^[23]
