Join the Marines is a 1937 American action film directed by Ralph Staub and written by Joseph Krumgold and Olive Cooper.

The film stars Paul Kelly, June Travis, Purnell Pratt, Reginald Denny, Warren Hymer and Irving Pichel.

Paula is planning to marry playboy Steve Lodge, but her father, a colonel with the Marine Corps, uses his influence to prevent the marriage.

Phil shows great physical strength and leadership qualities, and he is rapidly promoted to the rank of corporal, and later, the acting first sergeant.

He volunteers for duty in the South Seas and singlehandedly quashes a rebellion by challenging the natives to spear-throwing competitions that win their respect.
