The swallow-tailed bee-eater (Merops hirundineus) is a near passerine bird in the bee-eater family, Meropidae.
This species, like other bee-eaters, is a richly coloured, slender bird. Its colours and readily visible forked tail make it unmistakable. It is mainly green with a yellow throat, blue gorget and black eye stripe and beak. It can reach a length of 20–22 cm, including the long forked green or blue feathers. Sexes are alike.
