Ma Jae Kyung, formerly known professionally as Kyle, is a South Korean singer and former member of ROMEO (로미오). He graduated from Korea Art High School.

He made his debut in May 2015 (under the stage name Kyle) as the group's main vocalist with their first EP, "The Romeo". They were originally managed in a joint venture by Japanese company Pony Canyon and by South Korean company CT Entertainment. In 2016, CT was acquired by Hunus Entertainment (후너스엔터테인먼트) and took full control of the group's management.

After early releases, the group began promoting less and less until they went on hiatus in early 2018. While no official announcement was ever made, ROMEO silently disbanded in late 2019.

He enlisted for his mandatory military service on April 8, 2019, and was discharged on November 9, 2020.

He promoted with fellow member Lee Seung Hwan in a sub-unit called ROMEO S&J in 2022, and he reunited with Seung Hwan, Hyunkyung and Kangmin to participate in JTBC's "Peak Time" in mid-2023, but were eliminated in the preliminary round. He continues to appear as a contestant in survival shows.
