Nina Arsenault (born January 20, 1974) is a Canadian performance artist, freelance writer, and former sex worker who works in theatre, dance, video, photography, and visual art.

Arsenault grew up in a trailer park in Beamsville, Ontario. She has two master's degrees. At one point prior to her transition, Arsenault was an instructor at York University, where she taught acting.

She has said she realized that she was a trans woman in August 1996 and was fully mid-transition around 1998. By 2007, she had undergone over $150,000 in surgery during her transition, financed through work in the sex industry as a webcam model, a stripper, and a self-described "hooker (oral sex only)."

Prior to his murder conviction, Arsenault dated aspiring model Luka Magnotta around 2002, who she described as manipulative and self-destructive.

Arsenault wrote a regular column on transgender issues for 36 issues of fab, a biweekly Toronto-based LGBT magazine. Her last column was in early 2007.

She appeared on the television series Train 48 and KinK, as well as the Showtime movie Soldier's Girl.

She had a well-publicized encounter with Tommy Lee, wherein he flirted with Arsenault for some time before discovering that Arsenault was transgender and subsequently left in a hurry.

Arsenault appeared in a one-act play written for her by Sky Gilbert in November 2007 entitled Ladylike. She also wrote her own one-woman show called The Silicone Diaries, directed by Buddies in Bad Times artistic director Brendan Healy, which toured across Canada to sold-out houses and critical praise.
