Reviewed is the Chiropteran fauna of Bali Island. A previous checklist is up-dated by recent publications and complemented by an additional collection, comprising new species records. Bat records for neighbouring Nusa Penida are included, because species collected from this island are erroneously quoted for Bali. A total of 40 and ten species are documented for Bali and Nusa Penida, respectively. Of 35 species on a previous checklist for Bali, four should be deleted (including a Miniopterus species recorded by two different species names), ten others have been listed for Bali, but one of these erroneously, and at least two are doubtful, as no collected specimens are documented. Of the ten species on Nusa Penida, three are unrecorded from Bali, though often erroneously cited for this island.
