Downers Grove is a village in DuPage County, Illinois, United States. It was founded in 1832 by Pierce Downer, whose surname serves as the eponym for the village. Per the 2020 census, the population of the village was 50,247. It is a south-western suburb of Chicago located between I-88 and I-55.

Downers Grove was founded in 1832 by Pierce Downer, a farmer who traveled to Illinois from Rutland, New York, but was originally from Vermont. Downers Grove was named for a lush grove of old-growth bur oak trees surrounding the village, which stood out from the local savanna landscape. Its other early settlers included the Blodgett, Curtiss, Blanchard, Stanley, Lyman, and Carpenter families. The original settlers were mostly migrants from the Northeastern United States and Northern Europe. In 1839, Reverend Orange Lyman, a presbyterian minister, and his wife Maria Dewey Lyman arrived, and built what is believed to be the first home in Downers Grove. The first schoolhouse was built in 1844. In 1846, the Blodgett house was built by Israel and Avis Blodgett. It was the second (or third) home built in Downers Grove. Both the Lyman and Blodgett homes are of cultural significance, as they were both built by abolitionist families and served as former stops on the Underground Railroad.

The Chicago, Burlington and Quincy Railroad was extended from Aurora to Chicago through Downers Grove in 1864, boosting its population. The town was incorporated in March 1873. Its somewhat unusual spelling ("Apostrophe-free since 1873") remains a minor historical mystery.

In April 1947, the wreck of a Burlington Railroad Twin Cities Zephyr passenger train killed three people, including the engineer. The streamliner struck a large tractor which had fallen from a freight train and two passenger cars crashed through a wall of the Main Street Station.

The construction of two major toll roads along the village's northern and western boundaries, I-355 in 1989, and what is now referred to as I-88 in 1958, facilitated the village's access to the rest of Chicago metropolitan area. I-55 is not far from the south edge of the village. Downers Grove has developed into a bustling Chicago suburb with many diverse businesses, including the headquarters for Devry University, FTD, Ambitech Engineering Corp, Dover, Heartland Food Corporation, and HAVI Global Solutions.

The housing stock in Downers Grove comprises a mixture; some, generally near the center of town, date from the middle of the 19th century, but housing styles of each succeeding generation are represented. Downers Grove has witnessed one of the highest teardown rates in the Chicago area; small older residences are being demolished and replaced with much larger new houses. Teardowns have been the source of much controversy within the village. Since they occupy much more land than the original houses, rainwater that was originally absorbed by their yards is directed into neighboring yards and streets, resulting in flooding. Concerns have been raised that teardowns reduce affordable housing in the town and promote gentrification.

According to the 2010 census, Downers Grove has a total area of 14.457 square miles (37.44 km2), of which 14.31 square miles (37.06 km2) (or 98.98%) is land and 0.147 square miles (0.38 km2) (or 1.02%) is water.
