Sonja Smits (1958) is a Canadian actress primarily known for her significant collaborations with director David Cronenberg. She left an indelible mark on genre cinema with iconic roles.

In *Videodrome* (1983), she played the sophisticated and mysterious Bianca O'Blivion, a key character in the protagonist's surreal journey. Subsequently, in *Inseparabili* (Dead Ringers, 1988), she delivered a more nuanced performance as Claire Niveau, the woman who complicates the lives of the Mantle twins.

Her acting style is characterized by an elegant and intellectual presence, often embodying strong, sometimes vulnerable women who navigate complex or destabilizing worlds. Although her film career is less prolific than her television career, these roles solidify her as a distinctive figure in Canadian auteur cinema.
