Kim Yoon-Sang (Hangul: 김윤상; born in 1934 ), was one of the senior most students of founder of hapkido, Choi Yong-Sool (Hangul: 최용술), from the hapkido founder's latter years. He is the notable Korean martial artist as the founder of Hapki yusul (Hangul: 합기 유술).
Kim Yoon-Sang began his study of Hapkido in the early 1960s under Master Chang Gedo, eventually reaching a grade of 5th Dan within the Korea Hapkido Association. In 1973, along with his friend Lee Yong-Soo (Hangul: 이용수), Kim travelled to Daegu to train under the founder of hapkido, Choi Yong-Sool. Thereafter Kim and Lee frequently travelled to Daegu to receive private lessons from Choi first at his school and then after it closed in 1976 in any available space.
At the request of Choi Yong-Sool, Kim and Lee opened up a school for training (see: dojang) in their hometown of Geumsan in 1978. In 1980 the school was named the Yong Sool Kwan (Hangul: 용술관) and Kim was appointed director of the school. After the establishing of this training facility Choi Yong-Sool often came to teach at the school and Kim and Lee continued to travel to Daegu to train with their master.
