Max Terhune (12 February 1891 Franklin, Indiana, – 5 June 1973 Cottonwood, Arizona), was an American film actor. He appeared in nearly 70 films, mostly B-westerns, between 1936 and 1956.

Terhune performed in 21 episodes of The Three Mesquiteers (co-starring with Robert Livingston and Ray "Crash" Corrigan in the Republic series); The Range Busters (24 entries with Ray Corrigan and John King at Monogram Pictures); several supporting roles with Gene Autry (at Republic), and the Johnny Mack Brown westerns at Monogram. Terhune played the comic sidekick (usually named either Lullaby Joslin or just Alibi)--with a major distinction. He always traveled the range with his dummy Elmer sharing his saddle.
