Oak Forest is a suburban city about 24 miles (39 km) south-southwest of downtown Chicago in Bremen Township in Cook County, Illinois, United States. The population was 27,962 at the 2010 census.Human habitation in Oak Forest began during the early Holocene. This is made evident by the remains of hunting camps on what would become the grounds of the city’s hospital. Several millennia later, the final known indigenous settlement in Oak Forest, a Potawatomi longhouse village, was established nearby. However, it was abandoned by the 1620s.The origins of present-day Oak Forest begins with a railroad whistle stop on the Chicago, Rock Island and Pacific Railroad 1 block south of the intersection of 167th street and Central Avenue which primarily served area dairy farmers.
This stop was located in a largely forested area of what was previously known as the Cooper’s Grove Stand of Timber. By the 1880s this particular area of timber was being referred to as the “Oak Forest” due to its abundance of oak trees. A section of the former “Cooper’s Grove Road” paralleling the railroad track from 66th Court to 167th Street in Tinley Park became known as “Oak Forest Avenue,” because it was the road from the Village of Bremen/New Bremen (now Tinley Park) that lead to this “Oak Forest.”
