Ali Abbasi (Persian: علی عباسی, born 1981, Tehran) is an Iranian-Danish filmmaker. He attended Tehran Polytechnic until 2002, when he emigrated to Europe to study architecture at the Royal Academy of Sciences in Stockholm. After earning his Bachelor of Arts in 2007, he enrolled at the National Film School of Denmark, earning his degree in 2011 with the short film M for Markus. He lives in Copenhagen but continues to hold an Iranian passport.

In February 2025, Abbasi was accused of groping an unnamed actor at a Golden Globes after-party hosted by Creative Artists Agency (CAA). No named witnesses publicly came forward about the alleged incident, however. Abbasi himself released a statement clarifying his account of what occurred. Initial reports suggested that Abbasi was dropped by his own representatives at CAA as well as by his management and legal teams, due to the incident, but Abbasi clarified in his statement that he himself had ended those relationships in "a long-term career decision".
