Cookie is a shōjo manga magazine published by Shueisha. The magazine is well known for it's publication of Nana by Ai Yazawa.
In 1996, the Ribon editing department at Shueisha began publishing a manga magazine called Ribon Teens which featured a mixture of both the then-new and popular Ribon manga artists like Ai Yazawa, Miho Obana, and Mihona Fujii, and classic Ribon manga artists like Jun Hasegawa, Koi Ikeno, and Aoi Hiiragi. This magazine was published a couple of times in 1996 and 1997 before folding. In 1999, Shueisha revived the Ribon Teens concept in a new magazine which soon received the title Cookie. The first issue of Cookie was soon published and the second issue followed in May 2000.
