The 8th Mechanized Infantry Division was a military formation of the Republic of Korea Army during the 20th Century.

The unit initially comprised the 10th, 16th and 21st Regiments. The 16th Infantry Regiment was originally activated as the 16th Regiment on October 28, 1948 at Masan and was first commanded by Lt. Col. Park Shi Ch'ang (Korean: 박시창).

It became part of I Corps after the first fall of Seoul. Was part of the defensive line to slow the North Korean advance from Seoul to Taejon. Fought in the Battle of Pusan Perimeter.

Supporting the Eighth United States Army advance towards China, the 24th Division and the attached British 27th Brigade positioned on the left, proceeded to the Chongchon; the ROK II Corps, with the ROK 1st Division, advanced on the right. To the east the 8th Division reached Tokchon, forty miles north of Pyongyang, during the night of October 23, and then turned north and arrived at Kujang-dong on the Chongchon River, about ten miles from Tokchon, two days later. After the Chinese intervention in the war, Chinese troops broke the defences of its 16th Regiment during the battle on October 31, 1950.

After the Chinese intervention and attacks in November 1950, the division was among five allied formations (including the ROK 6th, 7th, and 8th Divisions) that the U.S. Army judged 'were shattered units that would need extensive rest and refitting to recover combat effectiveness.'

December 1, 2011, 8th Infantry Division has finished the switch to mechanized infantry; and is currently part of the US and ROK Combined Division with its war time command being the US Army 2nd Infantry Division.
