Oh Sang Hyuk, known professionally as Yeon, is a South Korean singer, dancer, and former member of BTL (비티엘).

He made his debut in December 2014 when he joined as BTL's new lead vocalist. The group had debuted 7 months earlier with their first single, "Beyond The Limit", and he was added to the lineup in October for special stages of their debut song. He was not officially introduced until the following month.

The group was managed by Shinhoo Entertainment (신후이엔티; formerly known as Kiroy Company) but faced many financial and logistic issues after Kiroy merged with SI Entertainment and acquired Shinhoo (keeping that name) in mid-2015. The group did not release any new material after their debut, as their mini-album "Gold Moon" was completed but went unreleased when the agency went broke and closed down. They disbanded in April 2016.

After disbandment, he focused on personal activities, obtaining a hairdresser's license and briefly reunited with 3 other groupmates for the singing survival show "Peak Time" in 2023.
