Naperville ( NAY-p?r-vil) is a city in DuPage and Will counties in the U.S. state of Illinois, and a suburb of Chicago. Located 28 miles (45 km) west of Chicago, Naperville was founded in 1831 and is the fourth most populous city in Illinois. As of the 2020 United States Census, its population was 149,540.
In July 1831, Joseph Naper arrived at the west bank of the DuPage River with his family and friends to found what would be known as Naper's Settlement. Among those original settlers were Naper's wife Almeda Landon, his brother John with wife Betsy Goff, his sister Amy with husband John Murray, and his mother Sarah. Their arrival followed a nearly two-month voyage across three Great Lakes in the Naper brothers' schooner, the Telegraph. Also on the journey were several families who remained in the settlement that would become Chicago, including that of Dexter Graves who is memorialized in Graceland Cemetery by the well-known Lorado Taft statue "Eternal Silence" (also known as "the Dexter Graves Monument").
By 1832, over one hundred settlers had arrived at Naper's Settlement. Following the news of the Indian Creek massacre during the Black Hawk War, these settlers were temporarily displaced to Fort Dearborn for protection from an anticipated attack by the Sauk tribe. Fort Payne was built at Naper's Settlement, the settlers returned and the attack never materialized. The Pre-Emption House was constructed in 1834, as the Settlement became a stage-coach stop on the road from Chicago to Galena. Reconstructions of Fort Payne and the Pre-Emption House stand as part of Naper Settlement outdoor museum village, which was established by the Naperville Heritage Society and the Naperville Park District in 1969 to preserve some of the community's oldest buildings.
In 1855, Sybil Dunbar came to Naperville as its first recorded black female resident; she died in 1868 and was buried in Naperville Cemetery on Washington Street. A commemorative marker honoring her was placed in the cemetery in 2015.
After DuPage County was split from Cook County in 1839, Naper's Settlement became the DuPage county seat, a distinction it held until 1868. Naper's Settlement was incorporated as the Village of Naperville in 1857, at which time it had a population of 2,000. Reincorporation as a city occurred in 1890.
In 1887, Peter Edward Kroehler established the Kroehler Manufacturing Company's factory in Naperville along the Chicago, Burlington & Quincy tracks. Kroehler Manufacturing became the world's largest furniture manufacturer, and a major employer in Naperville. The company closed the Naperville factory in 1978. In 1987, the site was redeveloped into upscale commercial and apartment properties, as Fifth Avenue Station.
After the Chicago YMCA stated that Naperville was too small for its own YMCA building, Peter Kroehler led a campaign to build one, which kicked off June 22, 1909. Within 15 days, the town of 3,400 raised $26,260. The YMCA was opened on March 26, 1911, and it included the first ever swimming pool in Du Page County. In May 2020, it was announced that it would close after 109 years of being open, due to economic difficulties placed on them by the COVID-19 pandemic.
On April 26, 1946, Naperville was the site of one of the worst train disasters in Chicago history. Two Chicago, Burlington and Quincy Railroad trains, the Advance Flyer and the Exposition Flyer, collided 'head to tail' on a single track just west of the Loomis Street grade crossing. The accident killed 45 and injured approximately 127 passengers and/or crew members. This event is commemorated in a metal inlay map of Naperville on the southeast corner of the Nichols Library's sidewalk area. In 2012, author Chuck Spinner published The Tragedy at the Loomis Street Crossing which details the tragedy and gives the stories of the 45 persons who perished. On April 26, 2014, a memorial entitled Tragedy to Triumph was dedicated at the train station. The sculpture by Paul Kuhn is dedicated not only to the crash victims but also to the rescuers at the site.
A predominantly rural community for most of its existence, Naperville experienced a population explosion beginning in the 1960s and continuing into the 1980s and 1990s, following the construction of the East-West Tollway (now known as the Ronald Reagan Memorial Tollway) and Interstate 355 (originally known as the North-South Tollway, now the Veterans Memorial Tollway). It has nearly quadrupled in size as the Chicago metropolitan area's urban sprawl brought corporations, jobs, and wealth to the area.
The March 2006 issue of Chicago magazine cites a mid-1970s decision to make and keep all parking in downtown Naperville free to keep downtown Naperville "alive" in the face of competition with Fox Valley Mall in Aurora and the subsequent sprawl of strip shopping malls. Parking meters were taken down, parking in garages built in the 1980s and 1990s is free, and parking is still available on major thoroughfares during non-peak hours.
On June 20, 2021, an EF3 tornado went through Naperville, uprooting trees, injuring eight people, and damaging 231 homes. Of the 231, 143 sustained "major damage", 68 homes had "minor damage", 19 homes were named un-inhabitable, and 1 was destroyed. The path of the tornado went through the southeast portion of Naperville, which included Chesnut Creek, Ranchview, The Glens, Meadow Glens, Evergreen Woods, and Maplebrook subdivisions. 
According to the 2010 census, Naperville has an area of 39.323 square miles (101.85 km2), of which 38.77 square miles (100.41 km2) (or 98.59%) is land and 0.553 square miles (1.43 km2) (or 1.41%) is water.
Portions of the city of Naperville drain to the West Branch of the DuPage River within DuPage County. The Forest Preserve District ownership of a large amount of property along the West Branch has minimized development in flood plains and has helped reduce the damages from overbank flooding that have occurred in the county's more developed watersheds. The DuPage River Trail also runs along the DuPage river, which serves bikes and pedestrians. In the downtown Naperville area, the trail is briefly interrupted for the Riverwalk.
Naperville is located in six townships and two counties. In DuPage County, the Northwest portion is in Winfield Township, the Northeast portion is in Milton Township, the West central portion is in Naperville Township, and the East central portion is in Lisle Township.
In Will County, the Southwest portion is in Wheatland Township, and the Southeast portion is in DuPage Township. The largest number of Naperville residents live in Lisle Township, followed by Naperville Township.

In 1999, Naperville was designated a White House Millennium Community, due to the construction of the Moser Tower and Millennium Carillon. The tower was started with a community lead fundraising effort in 1998. The 158-foot-tall Moser tower is just on north of Aurora Avenue and at the base of Rotary Hill within the Riverwalk Park complex. The tower's design won an award for "Best Custom Solution" from the Precast/Prestressed Concrete Institute (PCI).
The Millennium Carillon is designated as one of the four largest carillons in the world, with 72 bronze bells weighing from 10 pounds to the 6-ton "Captain Joseph Naper Bell". It is one of only four in the world that span six octaves. It was dedicated in an Independence Day event on June 29, 2000, with a reception attended by over 15,000, and a performance by the Naperville Municipal Band and the Naperville Men's Glee Club and Festival Chorus. The Carillon is both manually and also computer-playable, with most performances done by hand, but with half the bells played by a computer-controlled system at set times during the day. At present, the Carillon is operational and tours are available after concerts. In 2004, the City of Naperville took over control of the community venture that had run out of money. The Tower would later open in July 2007 with funding for completion of the site coming from the City of Naperville.
The Naperville Park District manages and provides leisure and recreational activities for Naperville and nearby residents. The District was established by referendum in 1966. As of 2007, the Park District manages over 2,400 acres (10 km2) of open space, including over 130 parks and four sports complexes. The Park District also manages two golf courses, Springbrook and Naperbrook. In addition, the Park District is responsible for the Naperville Riverwalk, construction of which began in 1981, marking the 150th anniversary of the first Joseph Naper's settlement.

In addition, the riverwalk features the Dandelion Fountain, the Naperville Century Walk, the Riverwalk Eatery, and the Commander Dan Shanower-Sep 11 Memorial. The memorial also includes over 140 faces made by local school children symbolizing the casualties of September 11. The Naperville Riverwalk Commission has started a plan to expand the riverwalk greatly, in "Riverwalk 2031 Master Plan". Some of the details of this plan includes extending the riverwalk to Edward Hospital, building a new park as a "gateway to North Central College", and creating an east bank riverwalk path from the highlands subdivision, to the North Central College Campus. Some of the other facilities managed by the Park District include:
