Blackhat is a 2015 American action thriller film produced and directed by Michael Mann and starring Chris Hemsworth, Tang Wei, Viola Davis, and Wang Leehom. Hemsworth portrays a convicted hacker offered clemency for helping track down a dangerous cybercriminal. The title refers to the cybersecurity term "black hat," meaning a hacker with malicious intent.

The film premiered at the TCL Chinese Theatre in Los Angeles on January 8, 2015, and was released in theaters on January 16. Blackhat was a box-office bomb, earning only $19.7 million at the box office against a budget of $70 million. The film received generally mixed reviews, with criticisms focused on casting and pace, though the film appeared on some critics' year-end lists.

A re-edited director's cut of the film was released on home video in November 2023.
