The Hidden Fortress (Japanese: 隠し砦の三悪人, Hepburn: Kakushi Toride no San Akunin, lit. 'The Three Villains of the Hidden Fortress') is a 1958 Japanese jidaigeki adventure film directed by Akira Kurosawa, with special effects by Eiji Tsuburaya. It tells the story of two peasants who agree to escort a man and a woman across enemy lines in return for gold without knowing that he is a general and the woman is a princess. The film stars Toshiro Mifune as General Makabe Rokurōta and Misa Uehara as Princess Yuki while the peasants, Tahei and Matashichi, are portrayed by Minoru Chiaki and Kamatari Fujiwara respectively.

The Hidden Fortress was the fourth highest-grossing film of the year in Japan, and Kurosawa's most successful film up to that point. It was a significant influence on the 1977 American film Star Wars.
