The Ingalls 4-S was an experimental American locomotive built by Ingalls Shipbuilding immediately after World War II. Intended as the first of many Ingalls-built locomotives, it was the only one the company built. It served on the Gulf, Mobile and Ohio Railroad (GM&O) until it was retired in 1966; it was scrapped the following year.
