Julien Leclercq (born 7 August 1979) is a French film director, screenwriter and producer.

Julien Leclercq began his career in 2004 with the production of the short film Transit, in which he explored a retro-future world populated by half-flesh, half-metal beings. The short film got the attention of the producer Franck Chorot and Gaumont, who promptly offered Leclercq a budget of 8.7 million euros to produce his first feature film Chrysalis, the story of a police lieutenant (played by Albert Dupontel) who tries to find his wife's killer in a Paris of 2025. Leclercq returned to reality to undertake the ambitious project of L'Assaut, a film about the hijack of the Paris-Algiers flight in December 1994.
