Kemi Oba culture, ca. 3700—2200 BC, an archaeological culture at the northwest face of the Sea of Azov, the lower Bug and Dnieper Rivers and the Crimea. This was a component of the larger Yamna horizon.
The economy was based on both stockbreeding and agriculture. It had its own distinctive pottery, which is suggested to be more refined that that of its neighbors.
The inhumation practice was to lay the remains on its side, with the knees flexed, in pits, stone lined cists or timber-framed graves topped with a kurgan. Of particular interest are carved stone stelae or menhirs that also show up in secondary use in Yamna culture burials.
The Kemi Oba culture is contemporaneous and partly ovelapping with the Catacomb culture.
