The crested myna (Acridotheres cristatellus), also known as the Chinese starling, is a species of starling in the genus Acridotheres native to southeastern China and Indochina. It is named after the tuft of feathers on its forehead that resembles a crest.

The crested myna is typically found in open spaces near urban and agricultural areas. It is a popular cage bird and, as a result, has been accidentally released in a few places outside of its usual range. For example, this species was introduced around 1890 into the Vancouver region of British Columbia. It was initially successful, reaching a population in the thousands, however, it has since then gone locally extinct in the area.

Like many starlings, the crested myna is omnivorous. It will eat a variety of food including worms, grubs, grains, fruit, and even garbage. It is a highly beneficial bird to farmers, as it feeds on insects and does not attack crops.

In 1743 the English naturalist George Edwards included a picture and a description of the crested myna in his A Natural History of Uncommon Birds. He used the English name "Chinese starling or Black Bird". When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the crested myna with the other mynas in the genus Gracula. Linnaeus included a brief description, coined the binomial name Gracula cristatella and cited Edwards' work. The specific epithet cristatella is a Latin diminutive of cristatus meaning "crested" or "plumed". The crested myna is now placed in the genus Acridotheres that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot. It was previously placed in the genus Aethiospar, which included the mynas that had a fully feathered or tufted face. Acridotheres was formerly the group of bare-skin faced mynas. Now, the two genera form a new group that keeps the name Acridotheres.

Three subspecies are recognised:

The crested myna is named after the tuft of feathers that form a crest-like structure on its forehead that covers the bird's nostrils. It is mostly black with a slight green sheen. It has a couple of white wing patches under its wings which are more visible during flight. The tips and the base of the primaries are white. The tail feathers also have white tips with the exception of the middle pair. The under-tail coverts are black with a white tip. The adult's eyes are orange, its bill is pale yellow, and its legs are a dull dark yellow. Its bill is slender and very sharp. The males are slightly larger than the females. The female's crest is slightly less well-developed. Otherwise, there is no sexual dimorphism. The subspecies A. c. brevipennis, has proportionally smaller wings and a smaller bill. The feathers that form the crest are narrower than the ones from the nominate subspecies. A. c. formosanus is slightly smaller than the nominate subspecies and its bill is greenish-yellow. Its under-tail coverts are white and it has a more developed crest.

The hatchlings are born naked except for of a short gray down found on certain parts of the bird. In about 18 to 20 days, the juveniles become fully covered with brown feathers. The crest is usually not well developed at this stage. Immature crested mynas have blue-gray eyes.

The crested myna can be found in a wide range of habitats from urban to rural areas. In cities, it can be seen in the eaves of buildings, along roads and alleys, near gardens and parks, in parking lots. It can be found under bridges, in trees, in chimneys, and on roofs. In rural areas, it can be spotted on agricultural fields, in orchards and farmyards, near manure piles. It can be seen near plowed fields to take advantage of the invertebrates found in the tilled soil. It is often seen near cattle as it eats the insects around them. It is also commonly distributed in grasslands, fields and at the edge of forests.
