Benzotriyne or cyclo[6]carbon is a hypothetical compound, an allotrope of carbon with molecular formula C6. The molecule is a ring of six carbon atoms, connected by alternating triple and single bonds. It is, therefore, a potential member of the cyclo[n]carbon family.

There have been a few attempts to synthesize benzotriyne, e.g. by pyrolysis of mellitic anhydride, but without success as of 2011. Calculations suggest that the alternative cyclic cumulene structure, called cyclohexahexaene, is the potential energy minimum of the cyclo[6]carbon framework. It is unclear whether this second structure is an isomer or a limiting resonance structure.
