Oak Park is a village in Cook County, Illinois, United States, adjacent to Chicago. It is the 26th-most populous municipality in Illinois, with a population of 54,318 as of the 2020 census. Oak Park was first settled in 1835 and later incorporated in 1902, when it separated from Cicero. It is closely tied to the smaller town of River Forest sharing a chamber of commerce and a high school, Oak Park and River Forest High School.
Architect Frank Lloyd Wright and his wife settled in Oak Park in 1889, and his work heavily influenced local architecture and design, including the Frank Lloyd Wright Home and Studio. Over the years, rapid development was spurred by railroads and streetcars connecting the village to jobs in nearby Chicago. In 1968, Oak Park enacted an Open Housing Ordinance, which helped devise strategies to racially integrate the village and prevent white flight.
Oak Park became and remains a multicultural, politically progressive community, with 80% or higher voter turnout in every presidential election since 2000. Oak Park has several public transportation links to Chicago with Chicago Transit Authority access via the Green Line and Blue Line "L" train lines, as well as the Metra Union Pacific West Line Oak Park station downtown.
History
In 1835, Joseph and Betty Kettlestrings, immigrants from Yorkshire, England, staked out a farm and built a house near Lake Street and Harlem Avenue, west of Chicago. Once their children were born, they moved to Chicago for the schools in 1843, and moved back again in 1855 to build a more substantial home a bit east on their quarter section of land. More farmers and settlers had entered the area. Their land was called by several names locally, including Oak Ridge, Harlem, and Kettlestrings Grove. When the first post office was set up, it could not use the name Oak Ridge, as another post office was using that name in Illinois, so the post office chose Oak Park, and that name became the name for the settlement as it grew, and for the town when it incorporated in 1902.
By 1850, the Galena and Chicago Union Railroad (after that, the Chicago & Northwestern and now Union Pacific) was constructed as far as Elgin, Illinois, and passed through the settlement area. In the 1850s the land on which Oak Park sits was part of the new Chicago suburb, the town of Cicero. The population of the area boomed during the 1870s, with Chicago residents resettling in Cicero following the Great Chicago Fire of 1871 and the expansion of railroads and streetcars to the area. "In 1872, when Oak Park received its own railroad depot on the Chicago and Northwestern Railway, its rapid emergence as a residential suburb of Chicago began. In 1877, the railroad was running thirty-nine trains daily between Oak Park and Chicago; in the subsequent year, more railroads and streetcar lines, with increased service, came to link Oak Park and Chicago. As Chicago grew from a regional center to a national metropolis Oak Park expanded – from 500 residents in 1872 to 1,812 in 1890, to 9,353 in 1900, to 20,911 in 1910, to 39,585 in 1920. Oak Park thus emerged as a leading Chicago suburb."
A review of Oak Park's history by Wiss, Janny, Elstner Associates in 2006 further explains the importance of railroads and streetcars in the development of Oak Park:
The Village of Oak Park was formally established in 1902, disengaging from Cicero following a referendum. According to the local historical society, "The period 1892–1950 saw the construction of almost all of the housing stock in Oak Park, and most of the village's current buildings."
Oak Park has a history of alcohol prohibition. When the village was incorporated, no alcohol was allowed to be sold within its village limits. This law was relaxed in 1973, when restaurants and hotels were allowed to serve alcohol with meals, and was further loosened in 2002, when select grocery stores received governmental permission to sell packaged liquor. Today, alcohol, such as beer and wine, is easily accessible, with many bars and cocktail lounges around the village.

In 1889, Frank Lloyd Wright and his wife Catherine Tobin settled in Oak Park. He built many homes and the Unity Temple, his own church, in the village, before he left in 1911 to settle in Wisconsin. Oak Park attracts architecture buffs and others to view the many Wright-designed homes found in the village, alongside homes reflecting other architectural styles. The largest collection of Wright-designed residential properties in the world is in Oak Park. A distinct focus on historic preservation of important architectural styles began in the 1970s and continues, with many buildings marked as historically significant, and so far, three historic districts defined. Other attractions include Ernest Hemingway's birthplace home and his boyhood home, the Ernest Hemingway Museum, the three Oak Park homes of writer and Tarzan creator Edgar Rice Burroughs, Wright's Unity Temple, Pleasant Home, and the Oak Park-River Forest Historical Society.
In 2025 the village hall faced significant turnover, with nine senior officials leaving and citing a "toxic" workplace.
Geography
Oak Park is located immediately west of the city of Chicago. The boundary between the two municipalities is Austin Boulevard on the east side of Oak Park and North Avenue/Illinois Route 64 on the village's north side. Oak Park borders Cicero along its southern border, Roosevelt Road/Illinois Route 38, from Austin to Lombard; and Berwyn from Lombard to Harlem Avenue. Harlem/Illinois Route 43 serves as its western border, where between Roosevelt and South Boulevard, it borders Forest Park and between North Boulevard and North Avenue to the west it borders River Forest.
The entire village of Oak Park lies on the shore of ancient Lake Chicago, which covered most of the city of Chicago during the last Ice Age, and was the forerunner to today's Lake Michigan. Ridgeland Avenue in eastern Oak Park marks the shoreline of the lake, and was once an actual ridge. As with the geographical setup of the Chicago River, which connects to the present day Lake Michigan just north of the city's Loop, the ancient Des Plaines river once emptied into glacial Lake Chicago, making prehistoric Oak Park a "Plains river Delta" system. One of North America's four continental divides runs through Oak Park. This divide, a slight rise running north–south through the village, separates the Saint Lawrence River watershed from the Mississippi River watershed, and is marked by one plaque on Lake Street at Forest Avenue and another in the northwest corner of Taylor Park.
According to the 2010 census, Oak Park has a total area of , all land.

Architecture and historic districts

Frank Lloyd Wright spent the first 20 years of his 70-year career in Oak Park, building numerous homes in the community, including his own and the Walter Gale House. He lived and worked in the area between 1889 and 1909. One can find Wright's earliest work here, such as the Winslow House in neighboring River Forest, Illinois. Also, examples of the first prairie-style houses are in Oak Park. He also designed Unity Temple, a Unitarian-Universalist church, which was built between 1905 and 1908. Several well-known architects and artists worked in Wright's Oak Park Studio, including Richard Bock, William Eugene Drummond, Marion Mahony Griffin, and Walter Burley Griffin.
Many buildings in Oak Park were built by other Prairie School architects, such as George W. Maher, John Van Bergen, and E.E. Roberts.
Oak Park's housing stock reflects the decades of its rapid growth while it was part of the town of Cicero, and since 1902, when it became a village. Historic preservation has been a priority since an ordinance passed in 1972 and since revised. There are 2,400 historic sites in Oak Park, the majority of which are homes built in the Queen Anne, Prairie School and Craftsman styles of architecture. The Village of Oak Park displays these online on an interactive website. Three historic districts recognize the variety of styles often standing next door to each other. The three districts are Frank Lloyd Wright, Ridgeland-Oak Park, and Seward Gunderson, outlined on a map from the village. A fourth district is under consideration as of 2015, of 176 homes built by Thomas Henry Hulbert.
Ernest Hemingway spent the first six years of his life at 339 N. Oak Park Ave. The house was returned to its original 1890s Victorian heritage after restoration in 1992 and is open to the public for tours through The Ernest Hemingway Foundation of Oak Park.
The Art Deco-style main post office on Lake Street was designed by White and Weber in 1933. It is part of the Ridgeland-Oak Park Historic District.
