Song Yoon Hyeong, known professionally as Song, is a South Korean singer, dancer, and member of iKON (아이콘). He graduated from Hanlim Arts High School.

He joined YG Entertainment (YG엔터테인먼트) as a trainee in 2012 and became part of the agency's Team B. The team was completed when the 6th member was introduced months later. Then, in 2013, he participated in the Mnet reality survival show "WIN: Who Is Next", competing against other trainees in Team A for the chance to debut as a group. Ultimately, Team B lost, and Team A ended up debuting as WINNER.

In June 2014, Team B appeared in the reality survival program "Mix & Match", a follow-up of the original show, in order to determine the final members of YG's second project group. He was one of 3 Team B members who had to compete against 3 new trainees to see which one would earn one of the remaining spots.

After several delays, he finally made his debut in September 2015 as iKON's sub-vocalist, visual and center, with their first album, "Welcome Back". They already had a fanbase in South Korea, Japan and other countries in Southeast Asia, so they quickly became a successful rookie idol group, winning first places in music shows, holding concerts and fan meetings, and ranking high in all major song/digital charts in the country.

In December 2022, all members ended their contracts with YG Entertainment after 7 years. Fans were fearful about a possible disbandment, but 2 days later, all signed with 143Entertainment (143엔터테인먼트) to continue group activities. He decided to use his last name, Song, as his new stage name.

He enlisted for his mandatory service on August 13, 2024, and was discharged on February 12, 2026.
