The malachite kingfisher was described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name Alcedo cristata. The specific epithet cristata is from the Latin cristatus meaning “crested” or “plumed”. The adjective “malachite” in the vernacular name normally refers to the dark green colour of the copper containing mineral. This kingfisher has blue upperparts but has black banding with pale blue or greenish-blue on its forehead.
A molecular phylogenetic study published in 2007 confirmed that the most closely related species is the Malagasy kingfisher, (Corythornis vintsioides). The Malagasy kingfisher has a black bill and greenish crest, and is not quite as dependent on water as the African species. It is otherwise similar in plumage and behaviour to the more widespread malachite kingfisher. The São Tomé kingfisher and the Príncipe kingfisher were sometimes considered as distinct species but a study published in 2008 showed that they are both subspecies of the malachite kingfisher.
