Yoo Yeon-seong (Korean pronunciation: [ju.jʌn.sʌŋ]; born 19 August 1986) is a South Korean professional badminton player.

He specializes in doubles events and was ranked as high as No. 2 worldwide with his former partner, Ko Sung-hyun. The two also competed at the 2012 Summer Olympics. For a long time he played mixed doubles with Kim Min-jung, but later switched partners to play with Chang Ye-na, starting in 2011. Starting in late 2013, his men's doubles partner was Lee Yong-dae. Together, they reached a world ranking of No.1 in August 2014.

Yoo was among 4 players reported to be retiring and hanging up his national team jersey after the Rio Olympics but during the Korea Open that September, it was revealed that he would be continuing to play on the national team after his partner Lee Yong-dae retired. Yoo said that he wants to spend more time with his family. After he and Lee won the Korea Open title, Yoo played an additional 9 international ranking events but his name was finally removed from the Korean national team list a few weeks after the 2017 Singapore Open.
