Phra Nakhon Khiri () is a historical park in Phetchaburi, Thailand on a hill overlooking the city. The name Phra Nakhon Khiri means 'holy city hill', but locals know it better as Khao Wang, meaning 'hill with palace'.
The park consists of three building groups on the three peaks of the 95 m hill.
The site was registered as a historical park on 27 August 1979, with two of the palace buildings now housing a branch of the Thai National Museum.
