Project Rap Rabbit is a cancelled rhythm game formerly in development by NanaOn-Sha and iNiS for PlayStation 4 and Microsoft Windows.

The game, directed by Masaya Matsuura in collaboration with Keiichi Yano, is pitched as a revival of story-based rhythm games such as PaRappa the Rapper and Gitaroo Man, and features rap battle gameplay mixed with Japanese culture.

Project Rap Rabbit aimed to build upon the rhythm-based gameplay of the two companies' previous games, PaRappa the Rapper and Gitaroo Man.

[1] The campaign was criticised for featuring no gameplay footage and setting stretch goals at unreasonable levels.

[1][6] As a result of this failure, work on Project Rap Rabbit was discontinued and canceled until further funding could be found.
