The Mythopoeic Fantasy Award for Adult Literature is given to the fantasy novel, multi-volume novel, or single-author story collection for adults published during the previous year that best exemplifies “the spirit of the Inklings.” Books are eligible for two years after publication unless short-listed during their first year of eligibility. Books from a series are eligible if they stand on their own; otherwise, the series becomes eligible the year its final volume appears.

The Mythopoeic Fantasy Award for Young Adult Literature was established on a trial basis in 2024 and honors books for Young Adult readers (ages 13-18). Rules for eligibility are the same as for the Adult literature award. The category of borderline books will be determined by their intended audience as named by the publisher and author; many books include this information on their back covers.

The Mythopoeic Fantasy Award for Children’s Literature was established in 1992 and honors books for younger readers (ages 12 or younger) in the tradition of The Hobbit or The Chronicles of Narnia. Rules for eligibility are the same as for the Adult literature award. The category of borderline books will be determined by their intended audience as named by the publisher and author; many books include this information on their back covers. 
 
From 1971 until 1991, we gave one award for all fantasy literature.
