The Tibetan blackbird (Turdus maximus) is a species of bird in the thrush family Turdidae. It is found in the Himalayas from northern Pakistan to southeastern Tibet. Originally described as a separate species by Henry Seebohm in 1881, it was then considered a subspecies of the common blackbird until 2008, when phylogenetic evidence revealed that it was only distantly related to the latter species. It is a relatively large thrush, having an overall length of 23–28 centimetres (9–10 inches).

Both sexes may seem slightly hooded. It can be differentiated from the common black
