The chestnut-headed bee-eater (Merops leschenaulti), or bay-headed bee-eater, is a near passerine bird in the bee-eater family Meropidae. It is a resident breeder in the Indian subcontinent and adjoining regions, ranging from India east to Southeast Asia.
This species, like other bee-eaters, is a richly coloured, slender bird. It is predominantly green, with blue on the rump and lower belly. Its face and throat are yellow with a black eye stripe, and the crown and nape are rich chestnut. The thin curved bill is black. Sexes are alike, but young birds are duller.
This species is 18–20 cm long; it lacks the two elongated central tail feathers possessed by most of its relatives.
