Lincolnshire is a village in Vernon Township, Lake County, in the U.S. state of Illinois. The village is a northern suburb of Chicago. The population of Lincolnshire was 7,275 at the 2010 census. Lincolnshire was incorporated on August 5, 1957, from the unincorporated Half Day area when land was purchased to build a residential subdivision. The community underwent an aggressive era of expansion from 1983 to the 1990s. The Des Plaines River bisects the village, passing from north to south; Illinois Route 22 also divides the village into two parts, crossing the village from east to west.
Lincolnshire is home to the award-winning public Adlai E. Stevenson High School and to Laura B. Sprague and Half Day elementary schools and to Daniel Wright Junior High School that compose the elementary Lincolnshire-Prairie View School District 103. Many global corporations are located in Lincolnshire, including Aon Hewitt, Zebra Technologies, CDW, and Sysmex, generating a daytime population of over 20,000 people. The Village of Lincolnshire and other entities host several popular annual events, including 4 July celebration, Art Festival, National Night Out, and Boo Bash. The Village maintains a Police Department that closely collaborates with its local school districts. Lincolnshire manages a public works system at the direct expense of the village; it retrieves all of its water from the city of Highland Park, which derives its water from adjacent Lake Michigan. The village has a council–manager government and is a home-rule municipality. The mayor of Lincolnshire is Elizabeth J. Brandt.
