3 Chococo Factory is the debut single album by South Korean girl group Gugudan, released on November 8, 2017 by Jellyfish Entertainment and distributed by CJ E&M.

[1] It was their first release as an eight-member group, since member Soyee was on hiatus for recovering from a shoulder injury that she had since prior to her debut.

[4] On October 26, Gugudan shared an image teaser through their official SNS channels featuring the eight members wearing bright red outfits and appear to be posing in various parts of a chocolate making factory.

The normal version consists of a booklet, two photo cards, a poster, and a special, limited "golden ticket" that would only be included in 100 albums.

Gugudan held a media event at Yes24 Live Hall in Gwangjang-dong, Seoul before the release of the single album.
