The Old Donghe Bridge or Old Tungho Bridge (traditional Chinese: 舊東河橋; simplified Chinese: 旧东河桥; pinyin: Jiù Dōnghé Qiáo) is a bridge in Taitung County, Taiwan.

It was the longest bridge designed during the Japanese rule of Taiwan.

In 1953, the bridge was rebuilt due to damage caused by typhoon by maintaining the original height of the towers at each end.

At the northern end in Chenggong Township side, it has an arch-shaped pier and sits on top of hard limestone soil foundation.

At the southern end in Donghe Township side, it has framed pier and sits on top of soft sedimentary rock foundation.
