Phnom Bakheng () at Angkor, Cambodia, is a Hindu and Buddhist temple in the form of a temple mountain. Dedicated to Shiva, it was built at the end of the 9th century, during the reign of King Yasovarman (889-910). Located atop a hill, it is nowadays a popular tourist spot for sunset views of the much bigger temple Angkor Wat, which lies amid the jungle about 1.5 km to the southeast. The large number of visitors makes Phnom Bakheng one of the most threatened monuments of Angkor. Since 2004, World Monuments Fund has been working to conserve the temple in partnership with APSARA.
