Dongshih (東勢, Hakka: Tung-si) is an urban township in eastern Taichung County, Taiwan Province of the Republic of China. A majority of the residents are of Hakka ethnicity, making it an enclave in an otherwise non-Hakka county.
Buildings in Dongshih were severely demaged by Chi-Chi earthquake in 2001.
Note: There is a rural township with the identical name in Yunlin County. In fact the name is quite a common one based on geography.
