Puppets Who Kill is a Canadian television comedy series produced by PWK Productions and originally broadcast on The Comedy Network. It premiered in Canada in 2002, and Australia on The Comedy Channel in 2004. It has also been broadcast in India, South Korea and Germany. The series was on the digital network Hulu and is currently on CONtv and Tubi in the United States.

PWK began as a one-man live theatre show written and performed by comedian/puppeteer John Pattison at the Toronto Fringe Festival in 1995. It later morphed into the series, using the same dark topics and featuring some of the same puppet characters. In 1999, a pilot for Puppets Who Kill was produced for the Comedy Network and broadcast in January 2000. The network ordered the first season of 13 episodes, which was produced in the fall of 2001, held back by the network for one year, and finally broadcast in the fall of 2002. For the next 3 years, a new season of the series was produced every fall.

In Puppets Who Kill, Rocko the Dog, Cuddles the Comfort Doll, Buttons the Bear, and Bill the Ventriloquist Dummy are four puppets with anthropomorphic qualities including individual histories of delinquency and recidivism. Canadian courts sent each of them to a halfway house for puppets, operated by a hapless and somewhat incompetent social worker named Dan Barlow, played by Dan Redican.
