Plumbocene is an organometallic compound of lead with the chemical formula . It is a member of the class of . It is soluble in benzene, acetone, diethyl ether, and petroleum ether, and insoluble in water. Plumbocene is stable in cold water.[

Gaseous plumbocene is a bent metallocene with angle 135°, similar to stannocene. But crystalline plumbocene can instead adopt a chain structure, similar to manganocene.
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 or lead(II) iodide.
The decamethyl analog, (decamethylplumbocene), and the half-sandwich complexes, (lead(II) pentamethylcyclopentadienide tetrafluoroborate) and Cp*PbCl (lead(II) chloride pentamethylcyclopentadienide), are known as well.
