The Birnirkculture is an prehistoric Inuit civilization of the north coast of Alaska, dating from 500 to 900 CE and disappearing around 1000 CE.
It succeeded the Punuk and Old Bering Sea/Okvik cultures and is distingushed from those cultures due to different art and harpoon styles.
A burial mound of the Birnirkculture was discovered in the town of Wales; 16 more have been found in Barrow at the "Birnirk site," which is now a National Historic Landmark.
