The Bali tiger (Panthera tigris balica), also called the Balinese tiger, is an extinct subspecies of tiger found solely on the small Indonesian island of Bali. The tiger was one of three sub-species of tiger found in Indonesia along with the Javan tiger (also extinct) and Sumatran tiger (severely endangered)
It was the smallest of the tiger sub-species; the last tiger to be shot was in 1925, and the sub-species was declared extinct on September 27, 1937. Given the small size of the island, and limited forest cover, the original population could never have been large, and it is considered unlikely that any survive today.
The species became extinct due to habitat loss and hunting.
