Dark Fantasy was a literary fantasy and horror fanzine by Howard Eugene (Gene) Day (1951-1982).
Gene Day began publishing Dark Fantasy in 1973 in Gananoque, Ontario, Canada. A total of 22 issues were published, the last issue in 1980. Day was told by the printer that issues 12 and 13 were lost, but issue 12 was later reconstructed and printed after issue 19 had come out in 1979. Gene Day suddenly died, at age 31, before issue 13 could be reconstructed. Gordon Derevanchik published a special commemorative double issue of Dark Fantasy, #24/25, in August 1984 in tribute to Gene Day.

Dark Fantasy is noted for featuring the first publication of the "Imaro" stories of Charles Saunders. The lack of black protagonists and the stereotyped portrayal of black characters in heroic fiction, combined with a love of African culture, history and mythology, inspired Sauders to create the "Imaro" character and stories. Several issues featured these stories, and issue 18 was the "All Imaro Issue".
The story "Moon Over the Xingu" by George Diezel II is considered to be a part of the Cthulhu Mythos.
The Gene Day Award for Self-Publishers is an annual award in Day's honour given to Canadian self publishing comic book creators.
