Anne Stine Ingstad was a Norwegian archaeologist who, along with her husband explorer Helge Ingstad, discovered the remains of a Norse settlement at L'Anse aux Meadows in the Canadian province of Newfoundland and Labrador in 1960.

Helge Marcus Ingstad was a Norwegian explorer. In 1960, after mapping some Norse settlements, Ingstad and his wife archaeologist Anne Stine Ingstad found remnants of a Viking settlement in L'Anse aux Meadows in the province of Newfoundland in Canada. They were thus the first to prove conclusively that the Icelandic/Greenlandic Norsemen such as Leif Erickson had found a way across the Atlantic Ocean to North America, roughly 500 years before Christopher Columbus and John Cabot. He also thought that the mysterious disappearance of the Greenland Norse Settlements in the 14th and 15th centuries could be explained by their emigration to North America.
