The Chicagoan and Kansas Cityan were a pair of American named passenger trains operated by the Atchison, Topeka and Santa Fe Railway. They ran between Chicago, Illinois and Oklahoma City, Oklahoma. The trains were introduced as a Chicago–Wichita service in 1938 and extended to Oklahoma City the next year. A Kansas City–Tulsa connecting train, the Tulsan, was also introduced at that time. The Chicagoan and Kansas Cityan ran until 1968, while the Tulsan ran until 1971.
