Tricarbon (systematically named 1λ2,3λ2-propadiene and '''catena-tricarbon''') is an inorganic compound with the chemical formula (also written [C(μ-C)C] or ). It is a colourless gas that only persists in dilution or solution as an adduct. It is one of the simplest unsaturated carbenes. Tricarbon can be found in interstellar space and can be produced in the laboratory by a process called laser ablation.

== Natural occurrence == Tricarbon is a small carbon cluster first spectroscopically observed in the early 20th century in the tail of a comet by William Huggins and subsequently identified in stellar atmospheres. Small carbon clusters like tricarbon and dicarbon are regarded as soot precursors and are implicated in the formation of certain industrial diamonds and in the formation of fullerenes.
