Plumbocene is an organometallic compound of lead with the chemical formula {{chem2|Pb(C5H5)2|auto=1}}. It is a member of the class of metallocenes. It is soluble in benzene, acetone, ether, and petroleum ether, and insoluble in water. Plumbocene is stable in cold water.

Plumbocene is not commercially available. It may be synthesized by the reaction of sodium cyclopentadienide with a lead(II) source such as lead(II) nitrate{{cite journal | last1 = Fischer | first1 = E.
