The Jianzha Yellow River Bridge (尖扎黄河特大桥) is an under-construction steel railway bridge of the Sichuan–Qinghai railway across the Yellow River located on the border of Jianzha county, Huangnan prefecture and Hualong county, Haidong city, both in Qinghai, China.

The bridge is to be 1,596.2 m (5,237 ft) long, with a span of 366 m (1,201 ft).

The bridge is being constructed by China Railway Major Bridge Engineering Group, and was scheduled to be completed by the end of August 2025.
