Roscoe Ates (1892-1962) was an American film actor, primarily recognized for his pronounced stutter, which became his trademark on screen. A prolific character actor, he played comedic supporting roles in over 150 films, often portraying clumsy, nervous, or good-natured characters.

His career particularly flourished during Hollywood's Golden Age, where he was a familiar face, often employed as a comedic sidekick in numerous Westerns or comedies. Among his most memorable appearances include *Cimarron* (1931), winner of the Academy Award for Best Picture, where he had a prominent role as a vaudeville actor, and *The Champ* (1931). His stutter, though authentic, was often exaggerated for comedic effect, making him an instantly recognizable and beloved figure to audiences.
