Hello! Project Akagumi (紅組; Red Group) was one of two concert groups Hello! Project was split into during the Hello! Project 2005 Winter ~A HAPPY NEW POWER!~ concert tour. A DVD of Akagumi's concert was released as a fanclub-exclusive.

Akagumi performed at the same venues as the Shirogumi, but alternated shows. At the end of each concert, Shirogumi would join Akagumi on stage and they would perform together as H.P. All Stars.
