The Flood Mythology of China, or Great Flood of China (Chinese: 大洪水; pinyin: Dà Hóngshuǐ; also known as Chinese: 洪水; pinyin: Hóngshuǐ) is a deluge theme which happened in China. Derk Bodde (1961) stated that "from all mythological themes in ancient Chinese, the earliest and so far most pervasive is about flood." The mythology also has shared characteristics with other Great Floods all over the world, although it also has unique characteristics or different focuses. Lu Yilu (2002) groups all versions of great flood into three themes: "the heroes controls the flood; "brother-sister marriage to repopulating the world"; and "the flood which is drowning the whole city along with its citizens".
