The Texas Special was a named passenger train operated jointly by the Missouri–Kansas–Texas Railroad (also known as the MKT or the Katy) and the St. Louis–San Francisco Railway (the Frisco). It was the flagship of both these lines, operating between St. Louis, Missouri, and San Antonio, Texas, from 1915 until 1959, after which time the Katy changed the northern destination from St Louis to Kansas City after the Frisco discontinued service from St. Louis.
