Emily Clark Huntington Miller (October 22, 1833 – November 2, 1913) was an American author, editor, poet, and educator who co-founded St. Nicholas Magazine, a publication for children.

Miller and Jennie Fowler Willing were involved with organizing a convention in Cleveland in 1874,[1] at which the National Woman's Christian Temperance Union was formed.

Thereafter, she was a constant and prolific contributor of sketches, short stories, serials, poems and miscellaneous articles to newspapers and magazines.

Her published literary work included 15 volumes, some of which were republished in England, and all of which found wide circles of readers.

She was prominently connected with the Woman's Foreign Missionary Society of the Methodist Episcopal Church, and was a Trustee of Northwestern University at Evanston, Illinois.
