Indium(III) sulfate (In₂(SO₄)₃) is a chemical compound. It may be formed by the reaction of indium, its oxide, or its carbonate with sulfuric acid.

The indium(III) cation is weakly oxidizing, and so it should be kept away from powdered aluminium and magnesium as it may react exothermically with it.
