Amund Ringnes Island is one of the Sverdrup Islands in Nunavut between 78 and 79 degrees of latitude. It lies east of Ellef Ringnes Island, west of Axel Heiberg Island. Hassel Sound separates Amund Ringnes Island from Ellef Ringnes Island.
Hendriksen Strait is to the south, as is Cornwall Island. Norwegian Bay is to the east, as is Haig-Thomas Island. To the north lies Peary Channel.
The island has an area of 5,255 km² (2,029 square miles) in size, making it the 111th largest island in the world, and Canada's 25th largest island.
The island was named by Otto Sverdrup for Oslo brewer Amund Ringnes, one of the sponsors of his expedition. The island was claimed by Norway from 1902 until the claim was relinquished in 1930.
