Banteay Srei or Banteay Srey is a 10th-century Cambodian temple dedicated to the Hindu god Shiva. Located in the area of Angkor, it lies near the hill of Phnom Dei, 25 km (16 mi) north-east of the main group of temples that once belonged to the medieval capitals of Yasodharapura and Angkor Thom. Banteay Srei is built largely of red sandstone, a medium that lends itself to the elaborate decorative wall carvings which are still observable today. The buildings themselves are miniature in scale, unusually so when measured by the standards of Angkorian construction. These factors have made the temple extremely popular with tourists, and have led to its being widely praised as a "precious gem", or the "jewel of Khmer art."

The temple was rediscovered in 1914 and was the subject of a celebrated case of art theft when André Malraux stole four devatas in 1923. (He was soon arrested, and the figures were returned.) The incident stimulated interest in the site, which was cleared the following year.

In the 1930s Banteay Srei was restored through the first important use of anastylosis at Angkor whereby a ruined building or monument is restored using the original architectural elements to the greatest degree possible. Until the discovery of the foundation stela in 1936, it had been assumed that the extreme decoration indicated a later date than was the case.
