Illinois (/ˌɪləˈnɔɪ/ (listen) IL-ə-NOY) is a state in the Midwestern United States. Chicago is its largest city, and the state's capital is Springfield; other major metropolitan areas include Metro East (of Greater St. Louis), Peoria and Rockford. Of the fifty U.S. states, Illinois has the fifth-largest gross domestic product (GDP), the sixth-largest population, and the 25th-largest land area.

Illinois has numerous museums; the greatest concentration of these are in Chicago. Several museums in Chicago are ranked as some of the best in the world. These include the John G. Shedd Aquarium, the Field Museum of Natural History, the Art Institute of Chicago, the Adler Planetarium, and the Museum of Science and Industry.

The modern Abraham Lincoln Presidential Library and Museum in Springfield is the largest and most attended presidential library in the country. The Illinois State Museum boasts a collection of 13.5 million objects that tell the story of Illinois life, land, people, and art. The ISM is among only 5% of the nation's museums that are accredited by the American Alliance of Museums. Other historical museums in the state include the Polish Museum of America in Chicago; Magnolia Manor in Cairo; Easley Pioneer Museum in Ipava; the Elihu Benjamin Washburne; Ulysses S. Grant Homes, both in Galena; and the Chanute Air Museum, located on the former Chanute Air Force Base in Rantoul.

The Chicago metropolitan area also hosts two zoos: The Brookfield Zoo, located about ten miles west of the city center in suburban Brookfield, contains more than 2,300 animals and covers 216 acres (87 ha). The Lincoln Park Zoo is located in Lincoln Park on Chicago's North Side, approximately 3 mi (4.8 km) north of the Loop. The zoo accounts for more than 35 acres (14 ha) of the park.
