Heo Yool (; born 12 April 2001) is a South Korean professional footballer who plays as a striker for K League 1 side Ulsan HD.
Heo made his professional debut for K League 1 side Gwangju on 30 May 2021 against Pohang Steelers.
Heo Yool drew attention for his ability to control the right to provide and dribble as a tall striker.
However, his offense failed to explode, so his team Gwangju tried to change his position to a defender by taking advantage of his left-footed advantage with special measures.
Although he performed well, he could not meet the demands of Gwangju FC, where the build-up from the back is the key. Now he has turned into a utility player who can play both strikers and defenders according to the situation.
