Kim Hyo Jung, known professionally as Hyolyn, is a South Korean singer, dancer, actress and former member of SISTAR (씨스타). She graduated from Inhwa Girls' High School and later obtained a bachelor's degree in Media Visual Arts from Sungshin Women's University.

She made her debut in June 2010 as the group's leader, main vocalist, lead dancer, lead rapper and face of the group with the single "Push Push". Starship Entertainment (스타쉽엔터테인먼트) wanted to create a group that was able to switch genres and become style icons. Their fourth single, "So Cool," debuted at #1 on the Gaon Digital Chart, starting a streak of 9 consecutive number-one hits for them. As of 2025, only 4 other artists (IU, 2NE1, BIGBANG, and TWICE) have nine or more #1 singles on Gaon.

In May 2011, she and Yoon Bo Ra formed the sub-unit SISTAR19 (씨스타19) and debuted with the single "Ma Boy", which also became a huge success.

However, Starship announced the group's disbandment in May 2017, much to the fans' disappointment, she also decided to leave the agency. They briefly reunited in July 2022 for an episode of "Yoo Hee Yeol's Sketchbook".

Then, in January 2024, SISTAR19 made a comeback with a new single titled "No More (Ma Boy)". The duo is managed by Klap Entertainment (클렙엔터테인먼트), and she is represented by her own agency, Bridge Entertainment (브리지엔터테인먼트) for individual activities.
