Madein (Korean: 메이딘; RR: Meidin), formerly known as LimeLight (라임라잇), is a South Korean girl group formed by 143 Entertainment. The group consists of MiU, Suhye, Mashiro, Yeseo, Serina, and Nagomi.

Madein originally debuted under the name LimeLight with a three-member line-up of MiU, Suhye, and Gaeun on February 17, 2023. The group announced their rearrangement in 2024 under the new name Madein, with four new members; adding former Kep1er members Mashiro and Kang Yeseo, and Produce 101 Japan The Girls contestants Serina Saito and Nagomi Abe. Gaeun left the group in November 2024 amid allegations that she was the target of sexual harassment by the CEO of the group's agency, which the company has denied.
