Chedi Phukhao ThongThai: เจดีย์ภูเขาทอง is a 50-metre chedi, or Buddhist tower, in the village of Phukhao Thong near Ayutthaya in central Thailand. Visitors can climb as far a landing halfway up the chedi, from which the surrounding rice fields and the town of Ayutthaya can be seen.
In 1569, having taken Ayutthaya, King Bayinnaung of Hongsawadi (now part of Myanmar) built a large chedi in the Mon style, next to the Buddhist temple of Wat Phukhao Thong, to commemorate his victory. Over the next two centuries the chedi fell into disrepair. In a restoration during the reign of King Boromakot (ruled 1733–1758) a new chedi in Thai style, having a square plan with indented corners, was built on the base of the ruin.  The adjacent temple, founded by King Ramesuan in 1387, is still in use.
