Oh Hyeon-gyu (; born 12 April 2001) is a South Korean professional footballer who plays as a striker for Süper Lig club Beà Âiktaà  and the South Korea national team.
Oh made his professional debut in K League 1 with Suwon Samsung Bluewings during the 2019 season, making eleven league appearances. He spent the next two seasons on loan at military club Sangju Sangmu (renamed Gimcheon Sangmu in 2021), where he served his military service. He returned to the Bluewings in the 2022 season and was the club's top scorer with 13 league goals.
On 25 January 2023, Oh joined Scottish Premiership club Celtic for an undisclosed fee, reported to be in the region of ã2.5 million, signing a five-year contract. He was assigned the number 19 shirt.
He made his debut on 29 January 2023, in a league game against Dundee United, replacing Kyogo Furuhashi in the 82nd minute of an eventual 2âÂÂ0 win. Then, he scored his first goal for the Bhoys on 11 February, in a 5âÂÂ1 Scottish Cup win over St. Mirren. Oh scored 11 goals during 36 league appearances including six starts, while usually playing as a substitute for main striker Furuhashi. However, he did not get playing time for half a year after Adam Idah came to the team on a loan deal.
On 14 July 2024, Oh signed a four-year contract with Belgian Pro League club Genk. On 22 September, he scored his first goal for Genk in a 4âÂÂ0 win over Dender. On 28 September, he led Genk's 2âÂÂ1 win by scoring twice, while playing 31 minutes as a substitute in the next Pro League match against Mechelen. He scored 1.33 goals per 90 minutes (9 goals in 610 minutes) as he played as a substitute for main striker Tolu Arokodare in his first season at Genk.
In the summer of 2025, Oh had a medical examination in Germany after receiving an offer from Bundesliga club VfB Stuttgart. However, the condition of his cruciate ligament did not satisfy Stuttgart, and they requested to convert his permanent move into a loan deal. He suffered a cruciate ligament injury in his boyhood, but his knee had no problems during his professional career until this point. Genk refused the request and cancelled his transfer. On 22 August, he scored his first goal at UEFA competitions in the UEFA Europa League play-off first leg against Lech Poznaà Â, which ended in a 5âÂÂ1 win. On 25 September, he scored the winning goal in a 1âÂÂ0 win over Rangers, the first league phase match at the Europa League. He played as a main striker for Genk during the first half of the 2025âÂÂ26 season, but his status at the club was lowered again after manager Thorsten Fink was sacked for poor results until December.
On 4 February 2026, Oh signed a three-and-a-half-year contract with Süper Lig club Beà Âiktaà Â, who paid a transfer fee of â¬14 million. On 8 February, he scored an equaliser and won a penalty in his first Süper Lig match against Alanyaspor, which ended in a 2âÂÂ2 draw. He also scored a goal in each of the two subsequent matches against ðstanbul Baà Âakà Âehir and Göztepe, becoming the first-ever Beà Âiktaà  player to score in all of the first three matches.
Oh represented South Korea at between under-14 and under-23 level. On 11 November 2022, he made his senior international debut in a friendly against Iceland. On 10 October 2024, he scored his first goal for the senior national team in a FIFA World Cup qualifier against Jordan, which ended in a 2âÂÂ0 win.
