Ta Prohm is the modern name of a temple near the city of Siem Reap, Cambodia, approximately one kilometre east of Angkor Thom and on the southern edge of the East Baray. It was built in the Bayon style largely in the late 12th century and early 13th century and was originally called Rajavihara. It was founded by the Khmer King Jayavarman VII as a Mahayana Buddhist monastery and center of learning dedicated to his mother. Almost 80,000 people were required to live in or visit the temple, including over 2,700 officials and 615 dancers.

Siem Reap is the second-largest city of Cambodia, as well as the capital and largest city of Siem Reap Province in northwestern Cambodia.
