Seong, also spelled Song or Sung, is an uncommon Korean family name, a single-syllable Korean given name, as well as a common element in two-syllable Korean given names. The meaning differs based on the hanja used to write it.

The family name Seong is written with only one hanja, meaning "succeed" or "accomplish" (). The 2000 South Korean Census found 167,903 people with this family name, up by six percent from 158,385 in the 1985 census. This increase was far smaller than the fifteen percent growth in the overall South Korean population over the same period. They traced their origins to only a single bon-gwan, Changnyeong County. This was also the place where they formed the highest concentration of the local population, with 2,360 people (3.61%).

In a study by the National Institute of the Korean Language based on 2007 application data for South Korean passports, it was found that 67.4% of people with this surname spelled it in Latin letters as Sung in their passports. The Revised Romanisation spelling Seong was in second place at 29.4%. Rarer alternative spellings (the remaining 3.2%) included Seung, Shung, and the Yale Romanisation spelling Seng.
