The Sintashta culture, also known as the Sintashta-Petrovka culture or Sintashta-Arkaim culture, is a Bronze Age archaeological culture of the northern Eurasian steppe on the borders of Eastern Europe and Central Asia, dated to the period 2100–1800 BCE. The earliest known chariots have been found in Sintashta burials, and the culture is considered a strong candidate for the origin of the technology, which spread throughout the Old World and played an important role in ancient warfare. Sintashta settlements are also remarkable for the intensity of copper mining and bronze metallurgy carried out there, which is unusual for a steppe culture.

Five cemeteries have been found associated with the site, the largest of which (known as Sintashta mogila or SM) consisted of forty graves. Some of these were chariot burials, producing the oldest known chariots in the world. Others included horse sacrifices—up to eight in a single grave—various stone, copper and bronze weapons, and silver and gold ornaments.

Sintashta is situated in the steppe just east of the Ural Mountains. The site is named for the adjacent Sintashta River, a tributary to the Tobol. The shifting course of the river over time has destroyed half of the site, leaving behind thirty one of the approximately fifty or sixty houses in the settlement.

The Sintashta economy came to revolve around copper metallurgy. Copper ores from nearby mines (such as Vorovskaya Yama) were taken to Sintashta settlements to be processed into copper and arsenical bronze. This occurred on an industrial scale: all the excavated buildings at the Sintashta sites of Sintashta, Arkaim and Ust'e contained the remains of smelting ovens and slag.
