The Three Natural Bridges (simplified Chinese: 天生三桥; traditional Chinese: 天生三橋; pinyin: Tiānshēng Sān Qiáo) are a series of natural limestone bridges located in Xiannüshan Town (仙女山镇), Wulong District, Chongqing Municipality, China. They lie within the Wulong Karst National Geology Park, itself a part of the South China Karst-Wulong Karst UNESCO World Heritage Site. In Chinese, the bridges are all named after dragons, namely Tianlong (Chinese: 天龙桥; lit. 'Sky Dragon') Qinglong (青龙桥; 'Azure Dragon') and Heilong (黑龙桥; 'Black Dragon').
