Blackhat is a 2015 American action thriller film produced and directed by Michael Mann, written by Morgan Davis Foehl, 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, by Universal Pictures. 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.
