Sadako DX (Japanese: [P DX) is a 2024 Japanese supernatural comedy horror film directed by Hisashi Kimura. The film is an installment in the Ring franchise, and a sequel to 1998's Spiral.

Chizuko Mifune, a famous psychic in the early 20th century, is an inspiration for Sadako and her mother Shizuko. Sadako is also based on the life of early-20th century psychic Sadako Takahashi, an apparent practitioner of nensha, the art of projecting

onto film by thought alone.
