Eastern Promises is a 2007 British-Canadian gangster film directed by David Cronenberg from a screenplay by Steven Knight. The film tells the story of Anna (Naomi Watts), a Russian-British midwife who delivers the baby of a drug-addicted 14-year old trafficked Ukrainian girl who dies in childbirth. After Anna learns that the teen was forced into prostitution by the Russian Mafia in London, the leader of the Russian gangsters (Armin Mueller-Stahl) threatens the baby's life, and Anna is warned off by his menacing henchman (Viggo Mortensen).

Principal photography began in November 2006, in locations in and around London. The film has been noted for its treatment of the subject of sex trafficking, and for its violence and realistic depiction of Russian career criminals, which includes detailed portrayal of the tattoos which indicate their crimes and criminal status. Eastern Promises received critical acclaim, appearing on several critics' "top 10 films" lists for 2007 and has since become a cult film. The film has won several awards, including the Audience Prize for best film at the Toronto International Film Festival and the Best Actor award for Mortensen at the British Independent Film Awards. The film received twelve Genie Award nominations and three Golden Globe Award nominations. Mortensen was nominated for the Academy Award for Best Actor.
