Samuel Morse Felton Jr. was an American railroad executive.

The Alton Railroad was the final name of a railroad linking Chicago to Alton, Illinois; St. Louis, Missouri; and Kansas City, Missouri. Its predecessor, the Chicago and Alton Railroad, was purchased by the Baltimore and Ohio Railroad in 1931 and was controlled until 1942 when the Alton was released to the courts. On May 31, 1947, the Alton Railroad was merged into the Gulf, Mobile and Ohio Railroad. Jacob Bunn had been one of the founding reorganizers of the Chicago & Alton Railroad Company during the 1860s.
