Atsuko Tanaka

is a Japanese animator. She has been involved with TMS Entertainment and many of Studio Ghibli's works. She is a member of the Japanese Animation Creators Association (JAniCA).

She is best known for her work on Lupin the Third, Little Nemo: Adventures in Slumberland, Animaniacs, Princess Mononoke, The New Batman Adventures, Spirited Away, Sonic X, Howl's Moving Castle, Ponyo, Belle, and The Boy and the Heron. In addition to her film work, Tanaka became a freelance animator in the early 2000s, working with studios such as Studio Chizu and Studio Ponoc after her long tenure at Telecom Animation Film. This shift allowed her to contribute to newer generations of Japanese animation, broadening her range beyond the classic films of the 1990s and 2000s. As a veteran animator in a male-dominated industry, her continued freelance work illustrated the evolving role and recognition of female creators in Japanese animation.
