Dibenzocyclooctatetraene is an organic compound with the formula (C₆H₄)₂(C₂H₂)₂. It is the bis(benzo) derivative of both cyclooctatetraene and 1,5-cyclooctadiene. The compound has received much attention as a strongly chelating diolefin ligand.

The compound can be made by coupling of xylylene dibromide to dibenzocyclooctane, which then can be converted to the diolefin.
