Song Ja Kyung, known professionally as Keena, is a South Korean singer, dancer and member of FIFTY FIFTY (피프티 피프티). She attended Lila Art High School before dropping out. She also went to GB Academy and spent more than 7 years as a trainee.

In 2019, she provided an OST for the drama "The Running Mates: Human Rights" (달리는 조사관) with the song "Take Back My Life".

She made her debut in November 2022 as the group's main rapper and sub-vocalist with the mini album “The Fifty”. The lead single, "Cupid", helped them become the fastest K-pop group to enter the US Billboard Hot 100 and UK Singles Chart (less than four months after debuting).

However, later that year, the members were involved in a series of legal disputes and allegations surrounding the group's contracts and treatment by Attrakt (어트랙트). Originally, all group members were involved, but she dropped the lawsuit. The other members had their contracts terminated, leaving her as the only remaining member in the label.

Attrakt later decided to re-debut FIFTY FIFTY in September 2024 with her and four new members. They released the mini album, "Love Tune".

On May 9, 2025, it was confirmed that she had halted activities due to PTSD. On July 7, 2025, it was announced that Keena would resume her group activities.
