Hololive Idol Project

 is the general brand for music by Japanese Vtuber agency Hololive. The brand is used mostly for songs commissioned by the agency itself rather songs by individual members which are released under their own name or their respective labels.

Structure
As a general brand, all members of Hololive (Japan, English, Indonesia) are also part of Hololive Idol Project. In practice, members typically release their music under their own name through Cover (Hololive's parent company), though members are able to sign up to different music label such as Tokino Sora (Victor Entertainment) or Mori Calliope (Universal Music Japan) or collaborate with a third party artist such as with Hoshimachi Suisei (Taku Inoue for Midnight Grand Orchestra).

In general, songs released as part of Hololive Idol Project are not strictly associated to any individual members and any combination of Hololive members can perform the songs at any point. The only exception are official units of specific combination of Hololive members which have songs associated only to them.

Units
This list only includes units which are officially part of Hololive Idol Project. Grouping such as Meltykiss (which are streaming collab units) or DeathStar (which are unofficial singing units not part of Hololive Idol Project) are not included.
