The 1034 Yellow River flood (traditional Chinese: 1034年黃河洪水; simplified Chinese: 1034年黄河洪水; pinyin: 1034 nián huánghé hóngshuǐ)[a] was a natural disaster along China's Yellow River originating in a burst fascine following heavy rainfall at Henglong in the territory of the Northern Song. The flood divided the Yellow River from its previous course into three more northerly channels meeting the Chihe, You, and Jin.
The Yellow River's new channels caused flooding in the rich northern regions of Dezhou and Bozhou, as well as reducing revenues in the northern regions of the Northern Song. The Yellow River flooded once again in 1048, causing the river's course to move northward past the southern Hebei-Shandong region, where it had led into the sea before.
