Janet Ellen Morris (born May 25, 1946) is a United States author. She began writing in 1976 and has since published more than 20 novels, many co-authored with David Drake or her husband Chris Morris. She has contributed short fiction to the shared universe fantasy series Thieves World, and edited the Bangsian fantasy series Heroes in Hell. Most of her work has been in the fantasy and science fiction genres, although she has also written several works of non-fiction.

Morris was elected to the New York Academy of Sciences in 1980.

In 1995, Morris and her husband and frequent co-writer Christopher Morris founded M2 Tech. Since that time, their writing output has decreased in proportion to the success of the company, which works with U.S. federal and military agencies on non-lethal weapon systems and software.
