The Baphuon is a temple at Angkor, Cambodia. It is located in Angkor Thom, northwest of the Bayon. Built in the mid-11th century, it is a three-tiered temple mountain built as the state temple of Udayadityavarman II[2]:103 dedicated to the Hindu God Shiva. It is the archetype of the Baphuon style.

The temple adjoins the southern enclosure of the royal palace and measures 120 metres east-west by 100 metres north-south at its base and stands 34 meters tall without its tower, which would have made it roughly 50 meters tall.
Its appearance apparently impressed Temür Khan's late 13th century envoy Chou Ta-kuan during his visit from 1296 to 1297, who said it was 'the Tower of Bronze...a truly astonishing spectacle, with more than ten chambers at its base.' In the late 15th century, the Baphuon was converted to a Buddhist temple.
