Dark Crimes is a 2016 crime drama film directed by Alexandros Avranas and written by Jeremy Brock. The film was based on a 2008 article in The New Yorker by David Grann titled "True Crime: A Postmodern Murder Mystery", about convicted murderer Krystian Bala who supposedly wrote a fictionalized novel about a murder he committed. The film stars Jim Carrey as a detective who notices similarities between a cold case murder and a best-selling novel. The supporting cast includes Agata Kulesza, Charlotte Gainsbourg, Kati Outinen, Zbigniew Zamachowski, and Marton Csokas.

Producer Brett Ratner had True Crimes in development since 2010. Principal photography began on 12 November 2015 in Kraków, Poland and ended a month later. It held its premiere at the Warsaw Film Festival on 12 October 2016 with the title True Crimes, and had a limited theatrical release in only a few countries, such as the United States, in 2018. Despite some praise for the cast, critics panned Dark Crimes for its pacing, overly downcast tone, and presentation of abused women. It is one of the worst-reviewed films of 2018, holding a 0% approval rating on Rotten Tomatoes.

To date, it is Jim Carrey's most recent film outside of the Sonic the Hedgehog film series.
