Terrace of the Leper King is the modern name for the royal platform at Angkor Thom (fig.), i.e. a Khmer edifice built in the Bayon style under King Jayavarman VII (fig.) and  assumingly used for funeral functions.

Located adjacent to the Terrace of the Elephants (fig.), the tall base of the deck is equally encased in intricate bas-reliefs, yet here of Hindu deities, Apsaras (fig.) and multi-headed nagas.

The designation purportedly derives from a 15th-century sculpture discovered at the site that depicts Yama, the Hindu god of death, which due to its imperfection, reminiscent of someone with leprosy, was nicknamed the Leper King.
