Paul Kenneth Bernardo (born August 27, 1964), also known as Paul Jason Teale, is a Canadian serial rapist and serial killer dubbed the Scarborough Rapist, the Schoolgirl Killer and, together with his former wife Karla Homolka, one of the Ken and Barbie Killers. He is known for initially committing a series of rapes in Scarborough, Ontario, a district of Toronto, between 1987 and 1990, before committing three murders with Homolka; among these victims was Karla's younger sister, Tammy Homolka.

After his capture and conviction, Bernardo was sentenced to life imprisonment and was declared a dangerous offender, thus making it unlikely that he will ever be released from prison. Following his conviction, Bernardo confessed to ten more rapes committed a year before the spree ascribed to the Scarborough Rapist. Homolka was given a lighter sentence in exchange for testifying against Bernardo as part of a controversial plea bargain; she was released from prison in 2005. Bernardo has been denied parole three times.
