Marjorie Benton Cooke (1876 - April 1920) was an American monologist, playwright, and novelist. A specialist in comic dramatic sketches and light romantic fiction.
She was born in Richmond, Indiana to Joseph Henry Cooke and Jessie Benton Cooke and attended the University of Chicago, graduating with a Bachelor of Philosophy degree in 1899.

She began working as a journalist soon after and by 1902 was touring the United States as a monologist. Several of her monologues and one-act plays were published in booklets and collected form. Her first novel, The Girl Who Lived in the Woods, was published by A. C. McClurg & Co. in 1910 and, like many of her future works, concerned the overcoming of conflicts between an unorthodox romantic couple.
