The 55th Homeland Defense Infantry Division (Korean: 제55향토보병사단) is a military formation of the Republic of Korea Army. The division is subordinated to the Ground Operations Command and headquartered in Yongin, Gyeonggi Province.

During the wartime, it functions as the regional reserve force in case the main army failed to stop the North Korean invasion through the front line.[1] [2]
It was founded under the name of 63rd Army Training Group in 1975. The unit isginia has a torch on it, which is also the origin of its nickname. At that time, subordinate units were also in Suwon and Pyeongtaek.
