Lee Yong-dae (Hangul: 이용대) (born September 11, 1988 in Hwasun, Jeollanam-do) is a male badminton player from South Korea. He is by many considered a great talent and already a wonderful player, often being called the 'new' Park Joo-bong.
Lee started playing badminton at his local elementary school at the age of 8. He joined the national badminton team of South Korea in 2003, at the age of just 15 years old. His current partners are Jung Jae-sung in men's doubles (as of 2006) and Lee Hyo-jung in mixed doubles (as of 2007).
Struggling to find the right partner, he played several tournaments, not getting any big results; only two semi-finals in the Asian Satellite. With Ha Jung-eun as his partner, they won Asian Junior Championship.
