The Life and Legend of Wyatt Earp is a western television series loosely based on the life of frontier marshal Wyatt Earp. The half-hour black-and-white program aired for 229 episodes on ABC from 1955 to 1961 and featured Hugh O’Brian in the title role.

O’Brian was chosen for the role in part because of his physical resemblance to early photographs of Wyatt Earp. The series was produced by Desilu Productions and filmed at the Desilu-Cahuenga Studio. Sponsors included General Mills, Procter & Gamble, and Parker Pen Company. An off-camera barbershop quartet sang the theme song and hummed the background music in early episodes. The theme song “The Legend of Wyatt Earp” was composed by Harry Warren. Incidental music was composed by Herman Stein.
