Death Note: Killer Within is a 2024 online multiplayer social deduction game developed by Grounding Inc. and published by Bandai Namco Entertainment. It is based on the 2003 manga series Death Note written by Tsugumi Ohba and illustrated by Takeshi Obata.

Both teams must uncover the identities of the opposing players.
