Choi Sung Min is a South Korean singer, dancer, actor and former member of COED SCHOOL (남녀공학) and SPEED (스피드). He graduated from Anyang Arts High School. He is the older brother of singer and former IZ*ONE member Choi Ye Na.

He made his debut in September 2010 as COED SCHOOL's lead vocalist and main rapper with their first digital single, "Too Late". However, MBK Entertainment (MBK엔터테인먼트, formerly known as Core Contents Media) opted to create two separate groups, one for the boys and another for the girls.

The newly formed boy group SPEED released a pre-debut single album titled "Hommage to Lovey-Dovey" in January 2012 as a tribute to T-ARA's "Lovey-Dovey". After some lineup changes, he officially re-debuted in January 2013 as SPEED's main dancer, lead vocalist, lead rapper, center and maknae with their digital single "Speed of Light".

In November 2015, MBK announced the group's disbandment. He left the company in January 2016.

He enlisted for his mandatory military service on July 23, 2019, and was discharged on February 13, 2021.

He has been represented by Star Camp 202 and by Management Air but is now an independent artist. He has appeared sporadically in some dramas, owned a café for nearly 1 year and also made his debut as a theater actor in mid-2023 and as a musical actor in late 2024.
