Bolingbrook is a suburb of Chicago incorporated in 1965. Similar to the neighboring village of Woodridge, almost all of the businesses, homes, churches and other buildings in Bolingbrook were built after 1960. The first settlement in what is now Bolingbrook was established in 1831, but the informal farming villages remained unincorporated for over 130 years. The area that is now Bolingbrook is located in the heart of the Gateway Wetlands, which begin in Downers Grove and end just north of the Joliet city limits. The tiny Boardman Cemetery, in what is now the Heritage Creek subdivision, contains the remains of some of these early residents.

Modern Bolingbrook has its roots in the housing boom of the 1950s. The first subdivision in Bolingbrook, known as Westbury, was immediately west of Route 53. A second subdivision, known as Colonial Village, followed on the far east side of Route 53.

The village continued to grow steadily for the remainder of the 1960s, reaching a population of 7,000 by 1970. The 1970s were the first period of rapid growth in Bolingbrook, during which its population quintupled to reach over 37,000 by 1980. Much of this growth was as much due to mass annexation as well as raw population growth; the population of Bolingbrook by the 1970 census but with its 1980 land boundary was approximately 25,000, further reflecting the vigorous annexation that took place during the 1970s.

By 1990, Bolingbrook's population had only increased by about 10% from the previous decade, to about 41,000.

As of 2019, 24 companies of various sizes have their corporate headquarters in Bolingbrook. The largest of these are the nation-wide cosmetic retailer Ulta Beauty and the vehicle floor liner manufacturer WeatherTech. Other corporate headquarters include: ATI Physical Therapy, Stevenson Crane, American Chrome, Computer Projects of Illinois, Diageo, Diamond Technical Services, Epir Technologies, Goya Foods' Illinois division, Midwest Fuel & Injection, G & W Electric, Illinois Paper & Copier, Jet Brite car washes, Wi-Tronix, Perkins Manufacturing, Vision Integrated Graphics, Clark Foam Products, Wastebuilt, COTG - Chicago Office Technology Group, and Windy City Wire.

According to the Bolingbrook Park District's 2017 Comprehensive Annual Financial Report, the top employers in the village are:

John J. "Jack" Leonard was instrumental in the village's incorporation and served as the village's first mayor.

In 1971, Bolingbrook purchased station 2 from the Lemont Fire Protection District, which had been serving much of the village, thus establishing its own fire department. Since then, that station has been expanded and four others have been built.

As of September 2024, the acting mayor of Bolingbrook is Mary Alexander-Basta. On July 31, 2020, longtime mayor Roger C. Claar resigned, having served in the role since 1986; Village Trustee Basta was unanimously appointed by the village board to complete Claar's term.

The Bolingbrook Park District was created in 1970, after being approved by referendum. In 1974, the Park District built its first new building, the Deatherage-Drdak Center, constructed only with volunteer labor. In the following three decades the Bolingbrook Park District has grown to include numerous woodlands and parks, several community centers, the Pelican Harbor Indoor/Outdoor Aquatic Complex, and the Bolingbrook Recreation and Aquatic Complex (BRAC). Most recently, the Bolingbrook Park District was one of the four finalists for the National Gold Medal Award for Excellence in Park Management, Facilities and Programs.

In 1982, the Park District opened the first indoor wave pool in the United States. It was closed shortly after the BRAC and Pelican Harbor opened in 1996, and has since been converted to an ice skating arena.

In 2009, the Park District opened its Hidden Oaks Nature Center, which sits on 80 acres of woodland and river plain habitat. The Nature Center has a Platinum LEED Rating from the U.S. Green Building Council and was built from recycled materials. As of 2014, the Nature Center is used to run naturalist programs and summer camps. Animal residents include: coyotes, deer, great horned owls, and other species common to Northern Illinois.

Bolingbrook is home to the Boughton Ridge Golf Course, a 9-hole course owned by the Bolingbrook Park District.
