Sharpe's drongo was described in 1879 by the French zoologistÉmile Oustalet from a specimen killed at Doume on the Ogooué River in Gabon. He coined the binomial nameDicrurus sharpei.[2] The specific epithet and the English name honours the English ornithologistRichard Bowdler Sharpe.[3] It was long considered a subspecies of the square-tailed drongo (Dicrurus ludwigii) but a 2018 study of genetic divergences indicated that both were distinct species. It can be physically distinguished from D. ludwigii by the lack of white tips on the axillaries as well as having a dull purplish-blue iridescence rather than the greenish blue-black iridescence of D. ludwigii.[4]
