Puffy (パフィー, Pafī, romanized as PUFFY) or Puffy AmiYumi is a Japanese pop/rock duo that is signed with Sony Music Japan. The group continues to go by the moniker of PUFFY in Japan, but in order to avoid legal naming conflicts with Sean Combs, have adopted the name Puffy AmiYumi in the United States. They sing in Japanese and English.

Ami Onuki, whose nickname is Jane, and Yumi Yoshimura, nicknamed Sue, were scouted by Sony-affiliated talent agencies and put together in the mid-1990s. The band gained mainstream success in Japan during 1998, following the release of their Jet album and tour in support of it.
