Park Jin U, known professionally as Jin Jin, is a South Korean singer, dancer and member of ASTRO (아스트로). He graduated from Hanlim Arts High School and is enrolled in the Broadcasting Entertainment program at Global Cyber ​​University.

He was formed through the rookie talent development program "iTeen Boys", which was created by Fantagio (판타지오). In August 2015, the final lineup for the agency's new group was revealed, and he appeared in the web drama "To Be Continued", which aimed to introduce them to the public. They also had concerts around South Korea and garnered a lot of attention even before officially debuting.

He made his debut in February 2016 as the group's leader, main rapper and lead dancer with their first EP, "Spring Up". They were quickly labeled as one of the best new K-pop acts of the year by Billboard.

However, Fantagio began facing internal issues, and the group released new material, but some were never promoted in any music show, and some lead singles did not have their corresponding MV. They spent much of 2017 traveling as they focused on having concerts and fan meetings around the world, but then had a 14-month hiatus without new material.

Starting in 2021, the members have mostly promoted as soloists and have been focused on their individual activities.

In January 2022, he debuted as part of the sub-unit JINJIN & ROCKY (진진&라키) with their first mini-album, "Restore". The unit disbanded when Rocky decided to leave the group in February 2023.

On June 2, 2025, Fantagio released an official statement announcing that Jin Jin was exempted from military service due to health-related concerns.
