The Sa Huỳnh culture or Sa Huyun was a culture in modern-day central and southern Vietnam that flourished between 1000 BC and 200 AD. Archaeological sites from the culture have been discovered from the Mekong Delta to Quang Binh province in central Vietnam. The Sa Huynh people were most likely the predecessors of the Cham people, an Austronesian-speaking people and the founders of the kingdom of Champa.:211–217
The site at Sa Huynh was discovered in 1909. Sa Huynh sites were rich in locally worked iron artefacts, typified by axes, swords, spearheads, knives and sickles. In contrast, bronze artifacts were dominant in the Đông Sơn culture sites found in northern Vietnam and elsewhere in mainland Southeast Asia.
The Sa Huynh culture cremated adults and buried them in jars covered with lids, a practice unique to the culture. Ritually broken offerings usually accompanied the jar burials. The culture is also typified by its unique ear ornaments featuring two-headed animals, believed by some to depict saola . The ornaments were commonly made from jade (nephrite), but also made from glass. Bead ornaments were also commonly found in Sa Huynh burials, most commonly made from glass.
The Sa Huynh culture showed evidence of an extensive trade network. Sa Huynh beads were made from glass, carnelian, agate, olivine, zircon, gold and garnet; most of these materials were not local to the region, and were most likely imported. Han Dynasty-style bronze mirrors were also found in Sa Huynh sites. Conversely, Sa Huynh produced ear ornaments have been found in archaeological sites in Central Thailand, Taiwan (Orchid Island) and the Philippines.
