Margaretta Muhlenberg Tuttle (née Perkins; September 2, 1875[1][2][3] – 1958)[4] was an American writer of the early 20th century.

Margaretta's father committed suicide by poison, leaving a note complaining of ill health.

Stories and articles by her started to appear in 1910, starting with the article "Maternity and the Woman Intellectual” (Collier's, January 29, 1910) and the story "The Greatest of These" (Ainslee's Magazine, Sept. 1910).

Tuttle wrote fiction and articles for markets such as Collier's, Ainslee's Magazine, Metropolitan Magazine, Harper's Weekly, the Women's Home Companion, the Ladies' Home Journal, Good Housekeeping, and the Saturday Evening Post from 1910 to 1932.
