Hideki Taniuchi is a Japanese composer who co-wrote the score for the Death Note anime, produced by Madhouse, alongside Yoshihisa Hirano.
Taniuchi shared composing duties with Yoshihisa Hirano on the 2006 Death Note anime, contributing to widely recognized cues such as "L's Theme" and the show's title track.

The soundtrack remains one of the more frequently cited anime scores of its era.

He went on to score the anime Real Drive, Akagi, and the gambling drama Kaiji, along with music for Aoi Bungaku and the Heian arc of Otogi Zoshi, frequently blending electric guitar riffs with orchestral and electronic elements suited to psychological drama.
