Uigorlersuaq Island (old spelling: Uigordlerssuaq) is an uninhabited island in the Qaasuitsup municipality in northwestern Greenland.
Uigorlersuaq Island is located in the outer belt of islands in Tasiusaq Bay, in the central part of Upernavik Archipelago. In the northwest, it is separated from a smaller Uigorle Island by the inner waterways of the bay. In the southeast, Ikerasak Strait separates it from Tasiusaq Island and Paagussat Island. It is one of the low-lying islands buffering Tasiusaq Island from the west. The highest point on the island is an unnamed 250 m (820 ft) peak in the northern part of the island.
