Tsukiuta (Japanese: ツキウタ。; stylized Tsukiuta.) is a character CD series that started as a collaboration between Vocaloid producers and popular voice actors but expanded into a media franchise with its own animation, multiple stage plays, manga anthologies, video games, and merchandise.

The characters of Tsukiuta are split into four idol groups under the fictional Tsukino Talent Production. There are twelve men and twelve women, each representing a month of the year. Tsukino Talent Production also manages the fictional idol groups under TsukiPro.

The men are split into rival units named Six Gravity and Procellarum. The members of Six Gravity come from Eastern Japan, while the members of Procellarum come from Western Japan.

The women belong to the units Fluna and Seleas. They are goddesses from a different dimension, unknown to anyone on Earth.
