Cook County, situated in the state of Illinois, holds the distinction of being the most populous county in the state and the second-most populous in the entire United States, following Los Angeles County, California. A staggering 40 percent of Illinois residents call Cook County home, with a population of 5,275,541 as of 2020. The county seat is Chicago, Illinois' most populous city and the third-most populous city in the United States. Central to the Chicago metropolitan area, Cook County boasts a pivotal location.

Established in 1831 and named after Daniel Pope Cook, an esteemed Illinois statesman, Cook County attained its current boundaries in 1839. Over the course of a century, it experienced remarkable population growth, evolving from a modest trading post village with just over six hundred inhabitants to a bustling metropolis of four million, rivaling Paris by the time of the Great Depression. In the first half of the 20th century, it claimed the majority of Illinois' population.

Cook County hosts over 800 local governmental units and nearly 130 municipalities, the largest of which is Chicago, housing approximately 54 percent of the county's entire population. The county's territory outside of Chicago and Evanston is divided into 29 townships, some of which share governmental services with local municipalities. While townships within Chicago were abolished in 1902, they are retained for real estate assessment purposes. Evanston Township, previously overlapping with the City of Evanston, was dissolved in 2014. Oversight of county government lies with the Cook County Board of Commissioners, while countywide state government offices include the Circuit Court of Cook County, the Cook County State's Attorney, the Cook County Sheriff, the Cook County Assessor, and Cook County Treasurer.

Of this area, 945 square miles (2,447.5 km2) are land and 690 square miles (1,787.1 km2) (42.16%) are water. The county's landscape is predominantly urban and densely populated. The state of Illinois capitalized on Cook County's access to Lake Michigan and the Chicago Portage, initiating with the construction of the Illinois and Michigan Canal in 1848, which transformed the region into a vital transit hub for the nation. Chicago, with its strategic position on the Great Lakes and access via the St. Lawrence Seaway, serves as a global port city, thus furnishing Cook County with an international shipping port.
