Janine Fuller (born 1958) is a Canadian businessperson and writer. She is the manager of Little Sister's Book and Art Emporium in Vancouver, British Columbia, and is best known for her role as an anti-censorship activist in the bookstore's ongoing battles with Canada Customs, which culminated in the Supreme Court of Canada case Little Sisters Book and Art Emporium v. Canada (Minister of Justice) in 2000.
Born and raised in Toronto, Ontario, Fuller began advocating for gender equality at a young age, fighting to be allowed to start a girls' soccer team in Grade 6. She was later an employee of the Toronto Women's Bookstore, and was working there when the store was firebombed in 1983. She moved to Vancouver in 1989, taking a job at Little Sister's the following year, and became an active fundraiser and freedom of expression activist as the store was drawn into legal battles when Canada Customs regularly confiscated and impounded its shipments from publishers.
Following a diagnosis with Huntington's disease in the late 2000s, Fuller has also become an activist and speaker on issues relating to the condition.
In 1995, she coauthored with Stuart Blackley the book Restricted Entry: Censorship on Trial, a non-fiction account of the Little Sister's battle, and wrote an introduction for Forbidden Passages: Writings Banned in Canada, an anthology of excerpts from some of the impounded works which was edited by Patrick Califia.
