The Archaeological Site in Wanggung-ri (Korean: 익산 왕궁리 유적) refers to the remains of a Baekje-era palace and temple in Wanggung-ri, Wanggung-myeon, Iksan, South Korea.

[1] In 2015, it was made a UNESCO World Heritage Site, as part of the item Baekje Historic Areas.

[1] It was used as a detached palace by the Baekje royal family, in order to offset the weak position of its main capital Sabi.

A large site for what is potentially the king's residence has been identified in the center of the complex; it has described as similar to a building in the Sabi royal palace.

[1] Of the site's remains, one of the most intact is the Five-story Stone Pagoda in Wanggung-ri [ko], a National Treasure of South Korea.
