The black-footed ferret (Mustela nigripes), also known as the American polecat or prairie dog hunter, is a mustelid species native to central North America. It is roughly the size of a mink and is similar in appearance to the European polecat and the Asian steppe polecat. It is largely nocturnal and solitary, except when breeding or raising litters.

It was declared extinct in 1979, but a residual wild population was discovered in 1981 in Meeteetse, Wyoming. A captive-breeding program launched by the United States Fish and Wildlife Service resulted in its reintroduction into eight western US states, Canada, and Mexico from 1991 to 2009. As of 2015, over 200 mature individuals are in the wild across 18 populations, with four self-sustaining populations in South Dakota, Arizona, and Wyoming. It was first listed as "endangered" in 1982, then as "extinct in the wild" in 1996 before being moved back up to "endangered" in the IUCN Red List in 2008.
