The Falkland Islands wolf, also known as the warrah and occasionally as the Falkland Islands dog, Falkland Islands fox, or Antarctic wolf, was the only native land mammal of the Falkland Islands. This endemic canid became extinct in 1876, the first known canid to have become extinct in historical times.

When Charles Darwin visited the islands in 1833 he found the species present in both West and East Falkland and tame. However, at the time of his visit the animal was already very rare on East Falkland, and even on West Falkland its numbers were declining rapidly.
