Are Tasmanian Tigers real

Yes - but they are now extinct.

The correct name for the Tasmanian Tiger was Thylacine, and they were a distant relative of the Tasmanian devil and the numbat. They were once found all over the Australian continent, but by the time Europeans settled in Australia, they were only known in Tasmania. They were dasyurids, meaning they were carnivorous marsupials.

The last known Thylacine died in the Hobart zoo in 1936.
