Ha Joon Young, formerly known as H-Jun, Hajun and E.co, is a South Korean singer, dancer, actor, producer and former member of J.RICH (제이리치) and JJCC (제이제이씨씨) and current member of 5TION (오션).

He made his debut (under the stage names Hajun and H-Jun) in 2010 as part of J.RICH with their first single, "Goodbye My Love". However, the group was not successful and went into hiatus after releasing a cheer song for the South Korean national team before the 2010 FIFA World Cup.

After switching agencies, he re-debuted in March 2014 as JJCC's vocalist and main rapper with their first single, "At First". As the group was created and managed by the Jackie Chan Group Korea, it gained some notoriety at the beginning. However, they faced a lack of promotion, and he decided to enlist for his mandatory military service in early 2017. While serving, the group went into an indefinite hiatus and finally disbanded officially in May 2024.

In 2020, he announced he was joining 5TION under his real name with the single "Final Destination" and later began promoting more in Japan.
