The 59-year-old German former striker, a World Cup winner as a player, was in the post for just under a year. "The KFA has decided to change the national head coach following a comprehensive review," Korea Football Association president Chung Mong-gyu said.
"Klinsmann has failed to display managerial capability and leadership expected of a national head coach in areas ranging from tactics, personnel management to work attitude and others required to bring about competitiveness.
"Klinsmann's attitude and competitiveness as head coach has fallen short of people's expectations and it was agreed that this would not be improved going forward, so we have decided to change leadership ahead of 2026 World Cup qualifying games." Klinsmann said it had been "an incredible journey" and thanked his players in a post on social media.
"The KFA will right away embark on finding the next head coach for the upcoming 2026 World Cup qualifiers."
