Sia (Chinese: ; pinyin: Shè; Pe̍h-ōe-jī: Sià) was a hereditary title of Chinese origin in colonial Indonesia, borne by the descendants of high-ranking Chinese bureaucrats in the Dutch colonial government (see: Kapitan Cina). Many title holders were eventually appointed to bureaucratic posts themselves by the colonial authorities. In the later colonial period, it became fashionable among western-educated title holders to refrain from using the title, which was seen as an old-fashioned anachronism.
