Mehdī Misāqīyeh (born in Tehran, 1927—1989) was an Iranian movie producer. Misāqīyeh began his career as an actor but soon joined other filmmakers in establishing the Kārun Film Studio (1952). He later founded Studio Misāqīyeh (1959), where he produced some of the most iconic movies of prerevolutionary Iran. Misāqīyeh’s innovations in technical fields, scene design, filming, editing, and even the use of music and sound, which was far ahead of his time, led to the improvement of the production quality of fiction films and made it possible to compete with foreign films at the box office. For example, at the age of thirty, he independently produced the movie Shabnishīnī dar jahannam (A Party in Hell; 1956), which was a great success at the box office in 1957. After his death in exile, many screenplays that were originally planned to be produced by his studio were approved for production and screening by the Islamic Republic.
