Tanquary Fiord[1] is a fjord on the north coast of the Arctic Archipelago's Ellesmere Island, Nunavut, Canada.

It is located in the Quttinirpaaq National Park and extends 48 km (30 mi) in a north-westerly direction from Greely Fiord.

[2] Radiocarbon analysis of charcoal undertaken by the Geological Survey of Canada has shown that Inuit were present at Tanquary Fiord around 1070 BP at the latest.

Carbon dating findings show that the fjord was free of glacial ice approximately 6,500 years ago.

A Warden Station is staffed by Parks Canada during the summer months,[8] and Tanquary Fiord Airport is located nearby.
