Thommanon (Khmer: ប្រាសាទធម្មនន្ទ) is one of a pair of Hindu temples built during the reign of Suryavarman II (1113–1150) at Angkor, Cambodia.

[2] Scholars studying the carvings of the devatas in Thommanon have concluded that it was built around the time when work on Angkor Wat was begun.

Some believe that the distinctive carvings of females, known as devatas, indicate that they were built during the reign of Jayavarman VI (1080–1113 AD), some time at the end of the 11th century.

However, there is greater agreement, especially given the scholarly studies, that it was built by Suryavarman II around the time of Angkor Wat and Beng Mealea from 1113 to 1150 AD.

[5] Thommanon is directly opposite the Chau Say Tevoda and just 500 metres east of the Victory Gate on the way to Ta Keo.

The devatas depict flower crowns, sampots (Cambodian skirts), necklaces, armbands, belts and ankle bands.
