Im or Rim is a common Korean family name equivalent either to the Chinese surname Lin or Ren depending on the clan branch.
The first clan branch is the Supul Rim (수풀 림, meaning Forest-Rim) and its Hanja character is 林. The Supul Rim branch consists of two large clan houses; the first is Naju (early Hoijin) and the second, which is the elder branch is Pyeongtaek. Members of this branch often write their names as both 임 (Im; more common) and 림 (Rim). The character 林 means "forest".
The second clan branch is the Matgil Im (맡길 임) or Mateul Im (맡을 임) and its Hanja character is 任. The Matgil Im/Mateul Im branch consists of one large clan house called Pungcheon (풍천) and a smaller clan house called Jangheung (장흥). Members of this clan branch both write and pronounce their names as 임 (Im). The character 任 means "trusted/to bear, duty".
When 林 (임/림) is romanized, it is usually spelled as "Rim", or occasionally as "Lim".
When 任 (임) is romanized, it is usually spelled as "Im", although is sometimes spelled "Yim".
Statistics from the year 2000 show that there were 762,767 수풀 림 (Rim/林) and 172,726 맡길 임 (Im/任) in South Korea.
