Janus was a science fiction fanzine published in Madison, Wisconsin, U.S.A. in the 1970s.
Janus was edited by Janice Bogstad for the first four issues, who was then joined by Jeanne Gomoll as co-editor. Their fanzine was one of the first feminist sf publications. The name of the fanzine was later changed to Aurora; 26 issues were released in total, 18 under the original name of Janus. It was closely associated with the Wisconsin Science Fiction Convention, or WisCon, and some issues of Janus also served as program books for the convention.
Contributors included John Bartelt and Tom Murn. Georgie Schnobrich contributed art work. Interviews with Suzy McKee Charnas and Amanda Bankier (The Witch and the Chameleon) were featured.
Janus was nominated for the Hugo Award for Best Fanzine from 1978 through to 1980. Jeanne Gomoll was nominated for the Hugo Award for Best Fan Artist for 1978 and 1980.
Jeann Gomoll continued publishing zines in the 1980s with her title Whimsey.
