Mission Hills is a city in Johnson County, Kansas, United States, and part of the Kansas City Metropolitan Area. As of the 2010 census, the city population was 3,498. The east city limits is the Kansas-Missouri state line at State Line Road. Mission Hills was originally developed by noted Kansas City developer J. C. Nichols beginning in the 1920s as part of his Country Club District plan.
An Indian mission was established at the town's site in the 1830s, hence the name of the later settlement.
The city started as a planned upscale community for the elite by J.C. Nichols to be built around the Mission Hills Country Club (Kansas) on the hills above Brush Creek just south of the Shawnee Methodist Mission. Most of the country club's property is in Kansas but its original clubhouse was in Kansas City, Missouri, allowing it to serve liquor, which was prohibited on the Kansas side. Nichols laid out plans in 1914. He had developed the country club to enhance the value of his Kansas properties after discovering that upscale buyers were reluctant to live on the Kansas side of the state line.
Adjoining the club Nichols established the Community Golf Club. After it dramatically grew, it moved to what today is the Kansas City Country Club. Nichols lured the Kansas City Country Club to take over the land, and the Community Golf Club went on to establish the Indian Hills Country Club.
