Park Gyu-ri, better known by the mononym Gyuri, is a South Korean singer, actress, and radio personality. She is a member of South Korean girl group Kara.

Kara is a South Korean girl group formed by DSP Media in 2007. The group's current lineup is Gyuri, Seungyeon, Nicole, Jiyoung, and Youngji. Kara made their debut in March 2007 with their first studio album, The First Bloooooming, and its title track, "Break It." Originally a quartet composed of Park Gyuri, Han Seungyeon, Nicole Jung, and Kim Sunghee, Kara showcased a strong female image and a mature R&B sound. Expectations for the group were high because they were considered the successors to their senior labelmates, Fin.K.L; however, their debut was a commercial failure. The following year, Sunghee left the group due to parental pressure, and members Goo Hara and Kang Jiyoung were added.
