《月亮不见了》是一部由中国台湾地区于2001年出品的剧情类电影。该片由现代著名作家担任编剧，蔡明亮亲自指导拍摄。主要演员包括赵自强、谭艾珍、李康生、刘亮佐、巧克力等中国台湾著名影星。
According to Tsai, the story is an odd, imaginary adventure tale. Playing the dog-man which eats the moon is Lee Kang-sheng. There will also be a transvestite grandmother, an astronaut and, of course, dozens of kids. Together they all fly to the moon, play hide-and-seek and have a party with a giant mooncake. For those familiar with Tsai's film-making style -- the grim depiction of human solitude, the urban anonymity of Taipei, the repressed emotions -- it's not easy to associate Tsai with a joyous, lively children's musical. But then the story is intended as an imaginary leap, according to Tsai. Tsai is, in fact, no a stranger to comedy, as his most recent film What Time Is It There? proved at its premiere in Cannes, where crowds erupted in laughter during the screening.
