Buffalo Grove is a village in Cook and Lake counties in the U.S. state of Illinois, within the northern suburbs of Chicago. As of the 2010 census, the village population was 41,496.
The official plat of the 210-acre town was approved by the U.S. Department of the Interior on November 22, 1902. Lots were sold in 1904â05. With 1907 statehood Grove, the only incorporated town in Delaware County, became the county seat. Located midway between the county's eastern and western borders, Grove was about five miles from the county's northern border with Ottawa County. This placement became a problem for residents who wanted a seat of government closer to the county's center.
