This is a list of the tallest dams in the world over in height. Currently, the tallest dam in the world is the Jinping-I Dam, an arch dam in China at high. The tallest embankment dam is the high Nurek Dam in Tajikistan, which is also the second tallest dam in the world. For gravity dams, the tallest is the high Grande Dixence Dam in Switzerland. When completed, the tall Rogun Dam also in Tajikistan could be the tallest, depending on the chosen design. Next in line are the  Bakhtiari Dam currently under construction in Iran and the  Shuangjiangkou Dam currently under construction in China. Natural landslide dams are also quite competitive in height, but are not listed here. In particular, the highest natural dam, Usoi Dam, is higher than the highest existing man-made one.
