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, as the group behind the zine had started the convention, and some issues of Janus also served as program books for WisCon.
Contributors included John Bartelt, Tom Murn, Jessica Amanda Salmonson (Windhaven) and Susan Wood (Aspidistra, Amor). Jeanne Gommoll and Georgie Schnobrich contributed art work. Interviews with Suzy McKee Charnas, and Amanda Bankier, editor of The Witch and the Chameleon, were featured. Letters came from Linda Bushyager (Granfalloon), and Ethel Lindsay (Scottishe), among others.
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.
