Sangiran, Archaeological site in Central Java, Indonesia.

Sangiran is an archaeological site in Central Java, Indonesia, spread over gentle hills and farmland along the Bengawan Solo River. Several small pavilions mark key excavation points where bones and stone tools emerge from the soil.

Sangiran was first reported in 1883 by P.E.C. Schemulling, and Eugène Dubois carried out preliminary fieldwork there before shifting to Trinil. From 1934 Gustav Heinrich Ralph von Koenigswald examined the dome, paying villagers for the "balung buta" bones they found; around 60 hominid fossils followed, including the Meganthropus series and Sangiran 2. The government designated 56 km² as a protected cultural area in 1977, and UNESCO listed the Sangiran Early Man Site in 1996.

Villagers once dug up fossils and sold them to local buyers, a trade that grew after Eugène Dubois found the Trinil skull in 1891. From 1934 Gustav Heinrich Ralph von Koenigswald paid residents for the "balung buta" (blind bones) they brought him. National Law No. 5 of 1992 on cultural heritage objects brought stronger controls, though illegal digging has sometimes continued.

The drive from nearby Surakarta takes about an hour by car or motorbike through rice fields and small villages. The terrain is open and flat, so visitors can walk easily between the pavilions and the museum building.

The bone remains often come from layers of volcanic ash, offering clues about large eruptions in the area during early human times. Some tools show signs of repeated reworking over many generations.
