Di-tert-butylcyclopentadiene is an organic compound with the formula (Me₃C)₂C₅H₄, where Me = methyl. It is a colorless liquid that is soluble in organic solvents. The compound is the conjugate acid of the di-tert-butylcyclopentadienyl ligand, (Me₃C)₂C₅H₃⁻ (sometimes abbreviated Cp^‡−). Two regioisomers of di-tert-butylcyclopentadiene exist, depending on the relative location of the double bonds.
