Lee Ah In

Name: Lee Ah In
Native name: 이아인
Also Known as: Cindy Lee, Ahin, Lee A In
Nationality: South Korean
Gender: Female
Born: September 27, 1999
Age: 26

Lee Ah In is a South Korean singer, dancer, and member of MOMOLAND (모모랜드). Her family moved to China when she was 6 years old, and she spent 11 years there. She graduated from Shanghai United International School and later returned to South Korea and graduated from Seoul Performing Arts High School.

She debuted in November 2016 as the group's main vocalist with their first mini-album, "Welcome to Momoland". The group, managed by MLD Entertainment (MLD엔터테인먼트; formerly known as Duble Kick Entertainment), was formed after the survival show "Finding Momoland". They had a few lineup changes when new members were added in 2017 but continued to actively promote in South Korea and Japan.

In 2020, their third mini-album, "Show Me", peaked at #2 on the South Korean Gaon Album Chart, and the group gained a dedicated fanbase at home and even in other countries. Unfortunately, the group's unique sound and limited discography made it difficult for them to gain mainstream recognition, and they disbanded in February 2023.

On April 10, 2025, it was announced that all 6 members of MOMOLAND signed exclusive contracts with Inyeon Entertainment.
