Geologfjord is a fjord in King Christian X Land, East Greenland.

The name was chosen owing to the spectacularly colored strata and rock formations in the shores of the fjord.

[2] It is a narrow and winding fjord located between mountains rising up to 2,100 metres (6,900 ft) on both sides, with cliffs displaying beautifully colored strata.

[2] The smaller Endeløs and Dukke Glacier flow into the fjord from the west.

[1] Bjorne Island, a rocky islet, rises close to the mouth of the fjord, north of Cape Weber, the easternmost end of Andrée Land.
