The black-headed kingfisher (Actenoides monachus capucinus) is a kingfisher in the subfamily Halcyoninae that is endemic to the eastern and southern regions of Sulawesi in Indonesia. It can be found in dense lowland forests up to 900 m (3,000 ft) elevation. It is threatened by habitat destruction by deforestation. The black-headed kingfisher is considered as a subspecies of the green-backed kingfisher (Actenoides monachus) by the International Ornithologists' Union but some taxonomists elevate the taxon to species status.
