Originally a settlement of the Papora people, this region was named Chinese: 沙轆社; Pe̍h-ōe-jī: Sa-lak-siā.

During the Kingdom of Tungning (1662－1683), the Taiwanese Plains Aborigines were driven away or sinicized, and the area became a Han settlement.

In 1920, during Japanese rule, the written name was changed to Sharoku (沙鹿).

Administratively, Sharoku was under Taikō District (大甲郡), Taichū Prefecture.
