Bactrian column idols are ancient stone objects of cylindrical or conical shape associated with the Bactria-Margiana culture of Central Asia, dating back to the 3rd and 2nd millennia BCE. They are believed to be religious or ritualistic artifacts, though their exact function is debated.

They have been found in various archaeological contexts, including funerary sites, sanctuaries, and caches, suggesting their importance in religious or ritual practices.  While their exact function is not known, they are thought to have been religious objects, perhaps used in rituals or as representations of deities. Some theories suggest they may have served as weights or counterweights.
