The eastern cave bat or Troughton's forest bat (Vespadelus troughtoni) is a species of vesper bat in the family Vespertilionidae. It is found only in Australia, where it lives in caves along the east coast of Queensland and New South Wales, and in adjacent inland ranges.

This species is similar in appearance to and may easily be mistaken for other microbats that share it's range, such as the large-footed myotis Myotis macropus.
