Park Sung Jun, known simply as Sungjun, is a South Korean singer, dancer and member of BOYS REPUBLIC. He graduated from Korea Open University with a bachelor's degree in English Language and Literature. Before debuting, he was a trainee at JYP Entertainment and later received two years of training under Universal Music and Jung Hae IK of Happy Tribe Entertainment.

He officially debuted in 2013 as the group's main dancer and lead rapper with their 1st single "Party Rock". The group had a successful debut charting #1 in several Asian countries and even earning the endorsement of Jeju Air. Universal Music Group began scheduling concerts and presentations around the continent and they steadily built a loyal fanbase throughout Asia with tours in Malaysia, Indonesia, Philippines, Japan and even expanding to Europe with a tour in 2015.

The following year, the group faced some controversy when the MV of the song "Get Down" included sexy and provocative scenes and blood splatting battle scenes which were a homage to the movie "Mad Max". The Korean censorship rated the video 19+ so it could not be aired in public TV. The group had to film a second version of the song in order to be able to promote in all music shows without being banned.

In 2017, he entered (alongside all his groupmates) the survival show "The Uni.T" but was eliminated in the earlier rounds. In September 2018, the agency announced that it had reach an agreement with all the members and after a concert on September 30, they went on an indefinite hiatus, a move that surprised many fans as they had enjoyed some success in the past 5 years.

The group has never announced an official disbandment and aside from a supporting role in the 2019 drama "Doctor Detective", he does not seem to be active in the entertainment industry.
