Khmer sculpture (Khmer: ចម្លាក់ខ្មែរ, Châmleăk Khmêr [cɑmˈlak kʰmae]) is the stone sculpture of the Khmer Empire, which ruled a territory based on modern Cambodia, but rather larger, from the 9th to the 13th century. The most celebrated examples are found in Angkor, which served as the seat of the empire.

Most of the sculpture is religious, reflecting the mixture of Hinduism and Buddhism followed in the empire. Large resources were devoted by the state to the erection of grand and highly decorated religious complexes, which often also serve to glorify the monarch.

There are several recognisable specific art styles of the Angkorian period:

Earlier Khmer art was heavily influenced by Indian treatments of Hindu subjects. By the 7th century, Khmer sculpture begins to drift away from its Hindu influences – pre-Gupta for the Buddhist figures, Pallava for the Hindu figures – and through constant stylistic evolution, it comes to develop its own originality, which by the 10th century can be considered complete and absolute. An example of Khmer style that totally departed from Indian sculpture tradition is the wholeness of its figure, which bears similarities to ancient Egyptian sculpture.

Unlike most Indian and Javanese Hindu-Buddhist stone sculptures, which were carved in high relief, or stelae supported by slabs at the figure's back, Khmer statues are carved wholly in the round. Khmer stone sculpture did not employ any stelae on the back of the figure to support it, as the result broken arms, hands or ankles vividly attest to the vulnerability of this format. Nevertheless, Khmer sculptors seems to wish their works to be seen from all sides in the garbagriha or sanctuary shrine in the center of the temple. Khmers attempted to make free-standing statues, supported by an arch or by an attribute of the divinity such as a piece of clothing or a hand-held object.

Khmer sculpture soon goes beyond religious representation, which becomes almost a pretext in order to portray court figures in the guise of gods and goddesses. But furthermore, it also comes to constitute a means and end in itself for the execution of stylistic refinement. The social context of the Khmer kingdom provides a second key to understanding this art. But we can also imagine that on a more exclusive level, small groups of intellectuals and artists were at work, competing among themselves in mastery and refinement as they pursued a hypothetical perfection of style.

The gods we find in Khmer sculpture are those of the two great religions of India, Buddhism and Hinduism. Priests supervised the execution of the works, attested to in the high iconographic precision of the sculptures. Nonetheless, unlike those Hindu images which repeat an idealized stereotype, these images are treated with great realism and originality because they depict living models: the king and his court. The true social function of Khmer art was, in fact, the glorification of the aristocracy through these images of the gods embodied in the princes. In fact, the cult of the “deva-raja” required the development of an eminently aristocratic art in which the people were supposed to see the tangible proof of the sovereign's divinity, while the aristocracy took pleasure in seeing itself – if, it's true, in idealized form – immortalized in the splendour of intricate adornments, elegant dresses and extravagant jewelry.

The sculptures are images of gods, royal and imposing presences with feminine sensuality, giving impressions of figures at the courts with considerable power. The sculptures represent the chosen divinity in the orthodox manner and succeeds in portraying, with great skill and expertise, high figures of the courts in all of their splendour, in the attire, adornments and jewelry of a sophisticated beauty.
