The flag of Cook County, Illinois, nicknamed "I Will", consists of a light blue pall with a green border on a field of white. Six red stars with seven points each sit in a circle at the flag's hoist side, drawing cues from the city flag and other symbols of the county seat of Chicago and its in-county suburbs.

Cook County is the largest county in Illinois by population. The current flag was adopted on June 14, 2022 (Flag Day). Winning a competition among almost 300 entries, the flag was designed by Drew Duffy, then a student at Glenbrook South High School, with the guidance of graphic designer Martin Burciaga from the Cook County Bureau of Administration.^[1]
