Dongshi District is a suburban district in eastern Taichung, Republic of China. It is the third largest district in Taichung City after Heping District and Taiping District. A majority of the residents are of Hakka ethnicity, making it an enclave in an otherwise non-Hakka county. Its Hakka dialect is very distinct compared to the dialects of other counties.
Dongshi is situated on a narrow, north–south oriented plain, flanked by the Da Jia River to the west and a mountain ridge to the east. It is this sense of being pressed up against that ridge, at the easternmost edge of the large west-central plain, that gives the town its name. Its elevation ranges from about 330 meters along the Dajia River to 1201 meters in the foothills of the Central Mountain Range.
