The Srubnaya culture (Russian: Срубная культура, romanized: Srubnaya kul'tura, Ukrainian: Зрубна культура, romanized: Zrubna kuljtura), also known as Timber-grave culture, was a Late Bronze Age 1900–1200 BC culture in the eastern part of the Pontic–Caspian steppe. It is a successor of the Yamnaya culture, the Catacomb culture and the Poltavka culture. It is co-ordinate and probably closely related to the Andronovo culture, its eastern neighbor. Whether the Srubnaya culture originated in the east, west, or was a local development, is disputed among archaeologists.
The Srubnaya culture is generally associated with archaic Iranian-speakers. The name comes from Russian сруб (srub) / Ukrainian зруб (zrub), "timber framework", from the way graves were constructed.
