Leah Rachel Clara Yoffie (April 15, 1883 – May 9, 1956) was an American writer, educator, and folklorist.

She was a teacher in St. Louis, Missouri, earned a Ph.D. in English in her fifties, and published both poetry and folklore studies influenced by her Jewish immigrant experience.

[4] She was encouraged by anthropologist Franz Boas to study Jewish immigrant culture in St. Louis, and many of her scholarly writings are on this subject.

[11][12] "There is a completeness and crystal clearness about each poem that is worthy of mention in this day of fragmentary poetry," wrote one reviewer in a St. Louis newspaper.

"Miss Yoffie has attained a singing quality and a certain sweep and power in some of her lyrics, rare in this day of poetic fads and unpoetic fancies.
