How the West Was Won is an American Western television series that starred James Arness, Eva Marie Saint, Fionnula Flanagan, Bruce Boxleitner, and Richard Kiley. Loosely based on the 1962 Cinerama film of the same name, it began with a two-hour television film, The Macahans, in 1976, followed by a mini-series in 1977, and a regular series in 1978 and 1979.

James Arness was an American actor, best known for portraying Marshal Matt Dillon for 20 years in the series Gunsmoke. He has the distinction of having played the role of Dillon in five decades: 1955 to 1975 in the weekly series, then in Gunsmoke: Return to Dodge (1987) and four more made-for-television Gunsmoke films in the 1990s. In Europe, Arness reached cult status for his role as Zeb Macahan in the Western series How the West Was Won. He was the older brother of actor Peter Graves.
