Hedong District (simplified Chinese: 河东区; traditional Chinese: 河東區; pinyin: Hédōng Qū) is located at the heart of the municipality of Tianjin, People's Republic of China.

In 1125, the territory of what would become Hedong District was part of Dazhigu, and fell under the control of Jin dynasty.

In 1404, the Ming dynasty built a series of military settlement on the southern bank of Hai River, causing the economic center of the region to shift south away from Dazhigu.

For the rest of the Ming dynasty, Dazhigu remained part of Jinghai county.

In 1924, Republic of China regain the control of Russian concession, and set it as the 3rd district.
