is a name created by the United States Postal Service to describe an area (Zip Code 662xx) of Johnson County, Kansas that contains numerous towns. The following towns are included in this area.
The name Shawnee Mission derives from the Shawnee Methodist Mission, a mission to the Shawnee tribe, founded in 1830 in present-day Wyandotte County, Kansas by the Methodist church. The mission was moved to what is now Johnson County in 1839. The county was named for Rev. Thomas Johnson, the first missionary sent by the church. The Shawnee Mission School District encompasses most of the area.
If the independent cities that constitute Shawnee Mission were to incorporate into a single municipality, its 2005 population estimate would be 355,260 (up from 325,147 in 2000), and would surpass Wichita as Kansas' largest city.
