Midlothian is a village in Cook County, Illinois, United States. The population was 14,315 at the 2000 census.
According to the United States Census Bureau, the village has a total area of 2.8 square miles (7.3 km²), all land.
Until the turn of the century, the area now known as the Village of Midlothian - named for an ancient borough in Scotland - was little more than a milk stop along the Rock Island Railroad serving a few area farmers. In 1900, a group of wealthy Chicago industrialists, looking for respite and retreat from the crowded city, discovered the green knolls and rolling fairways of the new Midlothian Country Club and golf course deciding they needed faster transportation, they petitioned the Rock Island to build a spur track, and soon passenger trains were speeding people from Chicago to the quiet little village.
