Han Seung-su (born September 10, 1986), commonly known as Seungsu Han, is a Korean-American professional golfer who plays on the Asian Tour and the Korean Tour. He has also played on the Japan Golf Tour, winning the 2017 Casio World Open. He also won the 2023 Kolon Korea Open.

Han was born in South Korea. He attended IMG Academy and was the first and only player to win all 5 AJGA Majors in one year during 2002. He also attended the University of Nevada-Las Vegas.^[2]

Han turned professional after earning a place on the 2009 Nationwide Tour. He had an unsuccessful first season on the Nationwide Tour, making the cut in only 6 out of 24 events he played and failing to retain his place on the tour. He played on the Asian Tour in 2010, again with little success. He played a few events on the Canadian Tour in 2012 and on the Japan Golf Tour in 2014.

Han played on the Japan Golf Tour again in 2016 with more success and has played regularly on the tour since then. His best season on the tour was 2017 when he won the Casio World Open, was runner-up twice and third a further three times. He finished the season 5th in the money list. He was also a runner-up in the Genesis Championship on the 2017 Korean Tour. His good performances in 2017 lifted him into the top 100 of the world rankings in late 2017 and for the first half of 2018, earning him an invitation to the 2018 PGA Championship, his first major championship. After a first round 74 he had a 66 to just make the cut and after further rounds of 66 and 72 he finished in a tie for 50th place.
