Nijū Mensō no Musume (Japanese: 二十面相の娘; lit. "The Girl of Twenty Faces") is a Japanese manga series written and illustrated by manga author Shinji Ohara. The manga was serialized in the seinen manga magazine Comic Flapper between 2003 and 2007, but continued serialization in the same magazine with the title Nijū Mensō no Musume Utsushiyo no Yoru since October 5, 2007. An anime adaptation aired in Japan from April 12, 2008, to September 27, 2008, and was co-produced by Bones and Telecom Animation Film.

The characters in this series have been used with permission from surviving members of the family of Edogawa Rampo, the Japanese detective fiction author who had originally created the fictional characters of Kaijin Nijū Mensō and Kogoro Akechi.

The series is set in the Shōwa period, starting around 1953 in the anime.
