Cerium(IV) sulfate, also called ceric sulfate, is an inorganic compound. It exists as the anhydrous salt Ce(SO4)2 as well as a few hydrated forms: Ce(SO4)2(H2O)x, with x equal to 4, 8, or 12. These salts are yellow to yellow/orange solids that are moderately soluble in water and dilute acids.

Cerium(IV) sulfate hydrate acts as oxidizing agent which is used for the generation of o-benzoquinone from catechol. It promotes the formation of radicals from dialkyl malonates, which undergo substitution reactions with furans and thiophenes.
