Head coach Juergen Klinsmann should be sacked, a Korea Football Association (KFA) advisory committee recommended on Thursday.
The development comes after their semi-final exit at the Asian Cup and criticism surrounding leadership, KFA Technical Director Hwangbo Kwan said.
The administrative decisions are not made by the National Team Committee, leaving it up to the KFA's Executive Board whether to act on its recommendation to fire Klinsmann, whose contract will continue till the 2026 World Cup.
South Korea, 23rd in the FIFA rankings, were defeated by 87th-ranked Jordan 2-0 in the Asian Cup last four earlier this month, which led to fans and politicians seeking the 59-year-old's dismissal.
The German's popularity in Korea reduced during the event, with many questioning his demeanour, smiling even when things were not going in favour of his team.
Klinsmann’s decision to repeatedly work in Los Angeles, where he currently lives, despite saying he would spend majority of his time in South Korea also has not gone down well with the locals.
He took part in Thursday's meeting via video call, the KFA said.
"For various reasons, there was a conclusion that coach Klinsmann can no longer exercise leadership as the national team's coach and needs to be replaced," Hwangbo told reporters after the meeting.
Some saw Klinsmann's attitude towards his job including time away from South Korea as "disrespectful" towards the public, Hwangbo added.
Ex-South Korean international Hong Myung-bo could temporarily take control of the team for the upcoming 2026 FIFA World Cup qualifier against Thailand if Klinsmann is ousted, according to Yonhap News TV.
Klinsmann, who won the World Cup in 1990 as a player, has previously worked with the German and U.S. national teams, as well as Bundesliga giants Bayern Munich.
He took charge of South Korea last year after Paulo Bento stepped down following their loss to Brazil in the Round of 16 of the World Cup in 2022.
The German's tenure got off to a poor start, with South Korea unable to win any of his first five games in charge, going down against Uruguay and Peru and drawing with Colombia, El Salvador and Wales.
South Korea's form improved before the start of the Asian Cup with a run of six straight wins, and despite being far from their best in Qatar, the Asian heavyweights improved on their quarter-final exit at the 2019 edition by reaching the semis.
In their semi-final defeat to Jordan, they were unable to register a single shot on target, falling short in their pursuit to end a 64-year wait for a third title.
