The Kelduá is a glacial river in eastern Iceland .
It is the outflow from the Kelduárvatn, north of the Vesturdalsjökull, from which the Jökulsá í Lóni also rises.
In the upper reaches this river is dammed to the Keldulón , which belongs to the Kárahnjúkar power station . About 9 kilometers before the Lögurinn the Kelduá flows into the Jökulsá í Fljótsdal .
