Rachel Crothers (December 12, 1878 – July 5, 1958) was an American playwright and theater director known for her well-crafted plays that often dealt with feminist themes. Among theater historians, she is generally recognized as "the most successful and prolific woman dramatist writing in the first part of the twentieth century." One of her most famous plays was Susan and God (1937), which was made into a film by MGM in 1940 starring Joan Crawford and Fredric March.
