The history of Cambodian art (Khmer: សិល្បៈខ្មែរ) stretches back centuries to ancient times, but the most famous period is undoubtedly the Khmer art of the Khmer Empire (802–1431), especially in the area around Angkor and the 12th-century temple-complex of Angkor Wat, initially Hindu and subsequently Buddhist. After the collapse of the empire, these and other sites were abandoned and overgrown, allowing much of the era's stone carving and architecture to survive to the present day. Traditional Cambodian arts and crafts include textiles, non-textile weaving, silversmithing, stone carving, lacquerware, ceramics, wat murals, and kite-making.

Beginning in the mid-20th century, a tradition of modern art began in Cambodia, though in the later 20th century both traditional and modern arts declined for several reasons, including the killing of artists by the Khmer Rouge. The country has experienced a recent artistic revival due to increased support from governments, NGOs, and foreign tourists.

In pre-colonial Cambodia, art and crafts were generally produced either by rural non-specialists for practical use or by skilled artists producing works for the Royal Palace. In modern Cambodia, many artistic traditions entered a period of decline or even ceased to be practiced, but the country has experienced a recent artistic revival as the tourist market has increased and governments and NGOs have contributed to the preservation of Cambodian culture.

Cambodia's best-known stone carving adorns the temples of Angkor, which are "renowned for the scale, richness and detail of their sculpture". In modern times, however, the art of stone carving became rare, largely because older sculptures survived undamaged for centuries (eliminating the need for replacements) and because of the use of cement molds for modern temple architecture. By the 1970s and 1980s, the craft of stone carving was nearly lost.

During the late 20th century, however, efforts to restore Angkor resulted in a new demand for skilled stone carvers to replace missing or damaged pieces, and a new tradition of stone carving is arising to meet this need. Most modern carving is traditional-style, but some carvers are experimenting with contemporary designs. Interest is also renewing for using stone carving in modern wats. Modern carvings are typically made from Banteay Meanchey sandstone, though stone from Pursat and Kompong Thom is also used.

The most ancient mural paintings of any kind in Cambodia attributed to the 10th-11th century, are those of Prasat Neang Khmau, located south of Kor Ker, depicting scenes with Hindu themes. However, little remains of them today. The earliest epigraphic evidence of painted scrolls appears inscription K. 285 dated to 1593 in Phnom Bakeng. The oldest documented Buddhist paintings are dated to 1877, consist of 14 small paintings (1 x 1.20 m), on cloth, illustrating episodes of the Vessantara Jataka. As in most Buddhist societies, stories from the lives of the Buddha are a common source of inspiration for the majority of paintings.

Because of destruction during recent war, few historic wat murals remain in Cambodia. In the 1960s, art historians Guy and Jacqueline Nafilyan photographed 19th-century murals, providing a record of this lost cultural heritage. The best known surviving murals are at the Silver Pagoda in Phnom Penh, Wat Rajabo in Siem Reap province, and Wat Kompong Tralach Leu in Kompong Chhnang Province. In the last decade, wat murals have seen a resurgence.

Preah Bot (Khmer: ព្រះបត), often called painted banners or scrolls, are paintings of Buddhist images on cloth incorporating a sewn tube at the top and base for inserting a wooden pole to hang the painting the keep it flat. The making of a preah bot is imbedded in the concept of merit-making through the production of a modest representation of devotion and the spreading of Buddhism. In 1899, Adhémard Leclère, a French scholar-administrator, wrote that painted scrolls were hung in monasteries and terraces to share the Dharma.
