Iron Horse is an American Western television series that appeared on ABC from 1966 to 1968 and starred Dale Robertson as fictional gambler-turned-railroad baron Ben Calhoun. Costars included Gary Collins, Robert Random and Ellen Burstyn. The series pilot was released as the film Scalplock.

Dayle Lymoine Robertson was an American actor best known for his starring roles on television. He played the roving investigator Jim Hardie in the television series Tales of Wells Fargo and railroad owner Ben Calhoun in Iron Horse. He often was presented as a deceptively thoughtful but modest Western hero. From 1968 to 1970, Robertson was the fourth and final host of the anthology series Death Valley Days. Described by Time magazine in 1959 as "probably the best horseman on television", for most of his career, Robertson played in western films and television shows—well over 60 titles in all.
