Hyeok-kyu Kwon (born 13 March 2001, age 25) is a South Korean midfielder from Busan. He first came to wider attention with Busan I'Park, where his most productive league season came in 2023, with two goals in 20 appearances.
Celtic signed him from Busan I'Park in July 2023 for around £860,000. It was a modest fee by modern standards, but still a clear enough move for a player expected to develop rather than arrive fully formed.
His Celtic spell did not become the settled stage of his career. He left in July 2025, joining Nantes for around £220,000, before further spells with Nantes and Karlsruher. Those moves sat between his time in Glasgow and a more established period back at Busan I'Park.
Now listed as Busan I'Park’s number 22, Kwon remains primarily a midfielder. His market value is around £850,000, according to Transfermarkt.
His career so far has been shaped by moves across South Korea, Scotland, France and Germany, with Busan I'Park still the club where he has looked most settled.
