Triosmium dodecacarbonyl is a chemical compound with the formula Os₃(CO)₁₂. This yellow-colored metal carbonyl cluster is an important precursor to organo-osmium compounds. Many of the advances in cluster chemistry have arisen from studies on derivatives of Os₃(CO)₁₂ and its lighter analogue Ru₃(CO)₁₂.
