Jeon Hyo Sung is a South Korean singer, dancer, actress and former member of SECRET (시크릿). She graduated from Gujeong High School and later obtained a bachelor's degree in Musical Studies from Woosuk University.

Before debuting, she was a trainee at Good Entertainment and was set to become part of FIVE GIRLS (오소녀) and debut in 2007. But, before they were able to debut, the agency faced financial issues that forced the members to switch agencies.

She made her debut in October 2009 as SECRET's leader, main dancer, lead vocalist and face of the group with the single "I Want You Back". The single was not successful, and TS Entertainment (티에스이엔티이알) brought some changes to the group's concept. In 2010, they released the singles "Magic" and "Madonna", and they saw a huge rise in popularity. Both singles reached 2nd and 1st place, respectively, in the Gaon Digital Chart, and they won the Newcomer Award at the 25th Golden Disk Awards.

The group enjoyed some commercial success until the departure of Han Sun Hwa in late 2016. By 2017, she filed a civil lawsuit against TS Entertainment to confirm the invalidity of her exclusive contract with the agency as TS transferred the management of her contract to another party without her consent.

In March 2018, she announced her departure from the group.

In July 2023, she signed an exclusive contract with Alien Company (에일리언컴퍼니) and is now focused on her acting career.
