Chlorobis(cyclooctene)rhodium dimer is an organorhodium compound with the formula Rh₂Cl₂(C₈H₁₄)₄, where C₈H₁₄ is cis-cyclooctene. Sometimes abbreviated Rh₂Cl₂(coe)₄, it is a red-brown, air-sensitive solid that is a precursor to many other organorhodium compounds and catalysts.

The complex is prepared by treating an alcohol solution of hydrated rhodium trichloride with cyclooctene at room temperature. The coe ligands are easily displaced by other more basic ligands, more so than the diene ligands in the related complex cyclooctadiene rhodium chloride dimer.
