Sophie Labelle (born circa 1987) is a trans author, cartoonist, and public speaker from Montreal,   known for her webcomic Assigned Male .   She is active in the transgender rights movement and speaks on the subjects of trans history and transfeminism.  
Labelle writes and draws Assigned Male , a webcomic and series of zines addressing issues of gender norms and privilege. It features the character of 11-year-old Stephie, a trans girl discovering and embracing her gender.    Labelle has said that while working with transgender children, she "noticed how negative everything we tell them about their own body is, so I wanted to create a character that could respond to all those horrible things trans kids hear all the time."  She has made educational guides to go with the comics, to promote safer spaces for trans youth.  The Washington Blade called the webcomic "hilarious" and said it shows transgender humour can be funny without being offensive. 
Labelle has written several books and zines about gender identity and expression, including The Genderific Coloring Book , A Girl Like Any Other , Ciel at Camp Fabulous , and Gender Euphoria .   She wrote the foreword to Tikva Wolf's book Ask me about Polyamory: The Best of Kimchi Cuddles .   She has created trans-centered sex education materials for Trans Student Educational Resources.  
In May 2017 Labelle released the comic book Dating Tips for Trans and Queer Weirdos . A scheduled launch at the bookstore Venus Envy in Halifax was cancelled after threats were made against both the store and Labelle. She received death threats, her home address was posted in online forums, and her web site and social media accounts were compromised (which she temporarily took offline).   In the wake of the harassment, Labelle advocated for Canadian Bill C-16 to protect gender identity and expression, and for stronger laws against cyberbullying.  She has also received criticism from other trans people who believe that the comic is harmful and against their core beliefs.
