Lloa is a group of Austronesian indigenous Formosan people living in the southern plain of Taiwan from Yunlin, Jiayi, to northern Tainan.^[1] They have lived through the Dutch colonization of Taiwan, as well as the Manchurian occupation during the Qing dynasty.^[2]

Lloa are generally classified together with the Hoanya and Arikun as a single group, which idea has been rejected by some scholars and the indigenous people themselves.^[2]
