The lake Sigöldulón () is a reservoir in Iceland, also known as Krókslón . Situated in the south of the country, not far from Landmannalaugar, it is one of the country's 20 largest lakes at 14 km<sup>2</sup>.
Both the lake and the nearby power station (Sigölduvirkjun ) take their names from a tuff ridge at about 600 m above sea level where the river Tungnaá once passed through a canyon. Its waters now flow in tubes into the power station, constructed between 1973 and 1977.
