The Egiin Gol (Mongolian: Эгийн гол) is a river in the Khövsgöl and Bulgan aimags in northern Mongolia.

It is the only outflow of Lake Khövsgöl and a left tributary of the Selenge river.

In Bulgan aimag there is a bridge between Teshig and Khutag-Öndör sums.

Since the early 1990s there have been efforts to build a hydroelectric dam on this river.

A dam would also displace parts of the local population as it floods some pastures and homesteads.
