The hairless bat or Naked Bulldog bat (Cheiromeles torquatus) is a species of free-tailed bats that is native to southeast Asia. They belong to the family Molossidae and are found in places such as Thailand, the Philippines, Borneo, Singapore, and Sumatra; and usually inhabit caves and other crevices.

This species of free-tailed bats are largely insectivorous and leaves the roost early in the morning to find prey. They are characterized and named after their hairless bodies and their bulldog-like appearance. There are a few patches on their bodies such as the first toe on their hind foot and their throat, where there are tiny fine hairs.

This species comes into the list of threatened species as one of Least Concern, which means that their habitat and lifespan face no immediate threat. However, habitat loss has caused them to relocate over the few years.
