The Village of Indian Hill is a city in Hamilton County, Ohio, United States, and an affluent suburb of the Greater Cincinnati area. The population was 5,785 at the 2010 census. Prior to 1970, Indian Hill was incorporated as a village, but under Ohio law became designated as a city once its population was verified as exceeding 5,000. The municipality then changed its name to add "Village" into the official name; legally it is "The City of The Village of Indian Hill".
