The Turkish Brigade, codenamed North Star (Turkish: Şimal Yıldızı or Kutup Yıldızı), was a military formation from Turkey that served under the United Nations Command during the Korean War.
Turkey was one of the 22 countries that contributed manpower to the United Nations in support of South Korea and one of the 16 countries that deployed military personnel to help in the fight against North Korea, which had precipitated the conflict by invading South Korea with support from the Soviet Union and the People's Republic of China. The brigade's first 5,000 Turkish troops arrived on 19 October 1950, shortly after the outbreak of hostilities in June of that year, and remained in varying strengths until the summer of 1954. Attached to the 25th Infantry Division of the United States, the Turkish Brigade was the only military formation of its size to have been permanently attached to an American military division for the duration of the Korean War.
