Kinloch is a city in St. Louis County, Missouri. The population was 263 as of the 2020 census. The oldest African-American community to be incorporated in Missouri, Kinloch was home to a vibrant and flourishing black community for much of the 19th and 20th century. It began to decline in the 1980s, when St. Louis began to buy up property due to an FAA noise-abatement program for nearby St. Louis Lambert International Airport.
