Tin(II) sulfate (SnSO₄) is a chemical compound. It is a white solid that can absorb enough moisture from the air to dissolve in it, forming a solution; this property is known as deliquescence. It can be prepared by a displacement reaction between metallic tin and copper(II) sulfate:

Sn (s) + CuSO₄ (aq) → Cu (s) + SnSO₄ (aq)

Tin(II) sulfate is a convenient source of tin(II) ions uncontaminated by tin(IV) species.
