Minimoni (ミニモニ。^?, also known as Mini Moni., mini-moni., etc.) is a former subgroup of Japanese pop girl group Morning Musume, and a current group within Hello! Project. They were one of Morning Musume's most popular subgroups for their entire existence, because^{[original research?]} of the combination of their outrageous music videos and live performances, and their widely varied musical styles.

The group was founded in late 2000 by Morning Musume member Mari Yaguchi, who had an idea for a subgroup whose members were 1.5 m (4 ft 11 in) in height or shorter. Yaguchi and Morning Musume's songwriter and producer, Tsunku, selected two of Morning Musume's newest members, Ai Kago and Nozomi Tsuji, for the new subgroup, and the trio began performing in concerts as Minimoni. American-born Mika Todd of Coconuts Musume was later added into the group to give the group "an international flavor" , and Tsunku made them official. Their debut single, "Minimoni Jankenpyon!", was a #1 hit.

An interesting side note is that Mika Todd usually wore drastically different costumes to her bandmates (while the other girls wore skirts and bows, Todd was often seen wearing jumpsuits or typically more masculine outfits). This could be attributed to her being the tallest member of the group^{[original research?]}, just making the height requirements at the band's founding. It is also possibly due to her being from Hawaii as opposed to the other members.^{[original research?]}
