The former Germany, Bayern Munich and United States coach succeeds Paulo Bento, who took the Koreans to the last 16 of the World Cup in Qatar, where they were beaten 4-1 by Brazil.
"You proved in Qatar that you can beat big nations, you beat Portugal in Qatar and four years ago you beat Germany, so you can do very well and this is our goal." Klinsmann had a successful playing career at clubs such as Inter Milan, Tottenham and Bayern, but some South Korean fans have questioned his record as a coach.
Klinsmann, who signed a three-and-a-half year contract with the Korea Football Association, added "I'm very proud and very privileged to have this opportunity to come to Korea and to work with the national team and to hopefully have success".
His first match will be a friendly against Colombia on March 24th.
