The shining-blue kingfisher (Alcedo quadribrachys) is a species of bird in the family Alcedinidae.

The shining-blue kingfisher was described of by the French ornithologist Charles Lucien Bonaparte in 1850 and given its current binomial name Alcedo quadribrachys.

[2][3] The name Alcedo is the Latin word for a "kingfisher".

The specific epithet quadribrachys is from the Latin quadri- for "four" and brachium meaning "arms" or in this case "toes".

[4] The shining-blue kingfisher is one of seven species in the genus Alcedo and is most closely related to the half-collared kingfisher (Alcedo semitorquata).
