Donghe Township (Chinese: 東河鄉; pinyin: Dōnghé Xiāng; Wade–Giles: Tung1-ho2 Hsiang1; literally: "east river township") is a rural township located in northeastern Taitung County, Taiwan.
Donghe Township has an old name of Fafukod (馬武窟), which means "fishing by net" in Amis language. Under Qing dynasty rule, the township was under jurisdiction of Pi-lam Subprefecture (卑南廳) and "Taitung direct-controlled state" (臺東直隸州) jurisdiction.
In 1920, during the period of Japanese rule, Toran local office (都蘭區役場) was set up. In 1937, it was changed to Toran Village (都蘭庄), under Shinkō District (新港郡), Taitō Prefecture. The name "Donghe Township" was established after World War II and is currently used.
It is bounded on the northeast by Chenggong, east by Pacific Ocean, west by neighboring Chihshang Township, Guanshan Township, and Luye Township, and south by Beinan Township.
