The archaeology of Indonesia is the study of the archaeology of the archipelagic realm that today forms the nation of Indonesia, stretching from prehistory through almost two millennia of documented history. The ancient Indonesian archipelago was a geographical maritime bridge between the political and cultural centers of Ancient India and Imperial China, and is notable as a part of ancient Maritime Silk Road. Today, the national institution of archaeology in Indonesia is the Pusat Arkeologi Nasional (National Archaeological Center).
