The Loner is an American Western television series that played for one season on CBS from 1965 to 1966, with the alternate sponsorship of Philip Morris and Procter & Gamble.

Lloyd Bridges played the title character, William Colton, a former Union cavalry captain who went to the American west in search of a new life.

Serling had expressed dislike for some of the television Westerns of the time in an editorial that described the premise for "Showdown with Rance McGrew", an episode of The Twilight Zone in which a primadonna Western actor encounters the ghost of Jesse James; in that editorial, he is quoted as saying: "it seems a reasonable conjecture that if there are any television sets up in cowboy heaven and any of these rough-and-wooly nail-eaters could see with what careless abandon their names and exploits are being bandied about, they're very likely turning over in their graves - or worse, getting out of them."

It debuted on September 18, 1965; the final episode was broadcast March 12, 1966; selected repeats continued through April 30.
