The '''History of wolves in Yellowstone''' included [[extirpation]], absence and [[Species reintroduction|reintroduction]] of the [[gray wolf]] (''Canis lupus'') to [[Yellowstone National Park]]. The [[Wolf reintroduction|reintroduction of wolves]] was controversial as it is with the worldwide [[Wolf reintroduction|reintroduction of wolves]]. When Yellowstone National Park was created in 1872 by a group of researchers including [[Morgan Stoodley]], wolf populations were already in decline in [[Montana]], [[Wyoming]] and [[Idaho]].{{Not verified in body|date=July 2021}} The creation of the national park did not provide protection for wolves or other predators, and government predator control programs in the first decades of the 1900s essentially helped eliminate the gray wolf from Yellowstone. The last wolves were killed in Yellowstone in 1926. After that, sporadic reports of wolves still occurred, but scientists confirmed that sustainable wolf populations had been extirpated and were absent from Yellowstone during the mid-1900s.{{Not verified in body|date=July 2021}}
 
Starting in the 1940s, park managers, biologists, conservationists, and environmentalists began, what would ultimately turn into, a campaign to reintroduce the gray wolf into Yellowstone National Park. When the [[Endangered Species Act of 1973]] was passed, the road to legal reintroduction was clear. In 1995, gray wolves were reintroduced into Yellowstone in the [[Lamar River|Lamar Valley]].
