Western Union is a 1941 American western film directed by Fritz Lang and starring Robert Young, Randolph Scott, and Dean Jagger. Filmed in Technicolor on location in Arizona and Utah. In Western Union, Scott plays a reformed outlaw who tries to make good by joining the team building a telegraph line across the Great Plains in 1861. Conflicts arise between the man and his former gang, as well as between the team stringing the wires and the Native Americans through whose land the new lines must run. In this regard, the film is not historically accurate; Edward Creighton was known for his honest and humane treatment of the tribes along the right of way and this was rewarded on the part of the Indians by their trust and cooperation with Creighton and his workers. The installation of telegraph wires was met with protest from no one.

The film is based on the 1939 novel Western Union by Zane Grey, although there are significant differences between the two plots.
