Man Without a Gun is an American Western television series produced by 20th Century Fox Television and presented on the NTA Film Network and in first-run syndication in the United States from 1957 to 1959. Set in the town of Yellowstone near Yellowstone National Park in the then Dakota Territory during the 1870s, the program starred Rex Reason as newspaper editor Adam MacLean, who brought miscreants to justice without the use of violence or gunplay but through his Yellowstone Sentinel. The co-star was Mort Mills, as Marshal Frank Tallman, who intervened when the "pen" proved not to be "mightier than the sword".^[1]Harry Harvey, Sr., was cast in twenty-one episodes as Yellowstone Mayor George Dixon.

The program is considered to have been unique because it showcased MacLean's moral ethics and common sense to bring outlaws to justice. The show was also used as a schoolroom to teach the youngsters of the 1950s about decency and the differences between right and wrong.^[2]
