The Reprua is a river in the Gagra District of Abkhazia, Georgia. Only 27 m (89 ft) long, it is one of the shortest named rivers in the world.

Sources of the river are the springs in karst Krubera Cave. The Reprua flows into the Black Sea, in the southwestern outskirts of Gagra.

The mountain rivers of Abkhazia may well compete with others for the title of the coldest waters of the world. Cold water in the Reprua River can be compared with spring water both in temperature and purity.

The name Reprua means “play of fresh water on the sea surface”.
