Lead(IV) sulfide is a chemical compound with the formula PbS2. This material is generated by the reaction of the more common lead(II) sulfide, PbS, with sulfur at >600 °C and at high pressures. PbS2, like the related tin(IV) sulfide SnS2, crystallises in the cadmium iodide motif, which indicates that Pb should be assigned the formal oxidation state of 4+.

Lead(IV) sulfide is a p-type semiconductor, and is also a thermoelectric material.{{cite journal|author=Cava, R.J. | title=Pressure Stabilized Se-Se Dimer Formation in PbSe2| journal=Solid State Sciences|year= 2011|volume= 13| issue=1| pages=38–41 | doi=10.1016/j.solidstatesciences.2010.10.003| bibcode=2011SSSci..13...38B}}
