The Buru dwarf kingfisher (Ceyx cajeli), is a species of bird in the family Alcedinidae that is endemic to Buru Island in Indonesia. Its natural habitat is subtropical or tropical moist lowland forests.

This species was formerly considered one of the 15 recognised subspecies of what was then known as the variable dwarf kingfisher (Ceyx lepidus or Alcedo lepidus).{{cite book | last1=Fry | first1=C.

At the same time the name of the variable dwarf kingfisher was changed to the Moluccan dwarf kingfisher.{{cite web| editor1-last=Gill | editor1-first=Frank | editor1-link=Frank Gill (ornithologist) | editor2-last=Donsker | editor2-first=David | year=2017 | title=Rollers, ground rollers & kingfishers | work=World Bird List Version 7.2 | url=http://www.worldbirdnames.org/bow/rollers/ | publisher=International Ornithologists' Union | access-date=17 May 2017 }}
