George Washington Moon (1823 – 1909) was an English writer, poet and critic of the late nineteenth and early twentieth century.

Moon published several poems, contributed to the Dictionary of National Biography, and wrote a number of books on English grammar. Several of these books were lengthy compilations of the purported grammatical errors of specific writers,^[1] which led to vigorous counterattacks and controversies.^[2]

George Washington Moon is the author of a book-length epic poem, Elijah the Prophet (1866). It was written in Spenserian stanza, a nine-line strophe with rhyme scheme ABABBCBCC.^[3][4]
