Ha Dae-Sung (Korean: 하대성; born 2 March 1985) is a South Korean football player who currently plays for the Chinese Super League club Beijing Guoan. He previously played for Ulsan Hyundai Horang-i, Daegu FC, Jeonbuk Hyundai Motors and FC Seoul.
Ha Dae-sung displayed exceptional footballing talent from early years. In 1997, Ha, who was then attending Incheon Mansoobuk Elementary School, was given the Grand Prize at the Cha Bum-kun Footballing Award, which is established by South Korean legend Cha Bum-kun to discover young talents. His reputation led Bupyeong High School, one of the most famous footballing schools in South Korea, to scout him. However, soon he got a crucial injury on his right knee and had to stop playing football for two years. On his senior year at high school, he began to play regularly. Soon, along with teammates Lee Keun-ho and Kim Seung-yong, Ha formed the famous Bupyeong Trio, helping his school win three national competitions.
Having failed at Ulsan, Ha moved to Daegu FC in 2006 and made his K League debut. With Lee Keun-ho, Ha began to shine and Daegu made a sensation in 2008 by playing an extremely aggressive football and becoming the joint top-scoring club in the league.
He moved to FC Seoul in 2010 and helped his club win the league in that season. On 3 January 2012, Ha was appointed captain of FC Seoul. After leading FC Seoul to another league championship, Ha Dae-sung received interest from various clubs. Dinamo Zagreb reportedly was one of the numerous clubs that made an offer to sign Ha. It was reported that a club from Qatar Stars League offered $2.5m as transfer fee to lure Ha. However, Ha chose to stay at FC Seoul.
