The Cook County Sheriff's Office (CCSO) is the principal law enforcement agency that serves Cook County, Illinois. It is the second largest sheriff's office in the United States, with over 6,900 members when at full operational strength. It is headed by the Cook County Sheriff, currently Thomas Dart.

Like other sheriffs' offices in Illinois, the Sheriff can provide all traditional law-enforcement functions, including county-wide patrol and investigations irrespective of municipal boundaries, even in the city of Chicago, but has traditionally limited its police patrol functions to unincorporated areas of the county because unincorporated areas are the primary jurisdiction of a Sheriff's Office in Illinois. The Sheriff's Police patrol services are often not required in incorporated cities because the cities such as Chicago have established their own police departments.

Sheriff's Deputies provide the other services of the sheriff, such as service of process, enforcing evictions and levies, securing courthouses, securing and operating the 9,000-plus detainee population of the Cook County Jail, transporting prisoners and overseeing offender rehabilitation programs.[2]
