was a Japanese idol project group formed by Up-Front Promotion in 2000 and associated with Hello! Project. Beginning in 2000, the Shuffle Unit project was a yearly collaboration among existing Hello! Project acts, where members were recombined into three different groups to release a single for each.

After a four-year hiatus, the project was briefly revived in 2009, where several old sub-groups saw a return under new names and new members. After 2009, the project became defunct.
