Vanadium(III) sulfate is the inorganic compound with the formula V₂(SO₄)₃. It is a pale yellow solid that is stable to air, in contrast to most vanadium(III) compounds. It slowly dissolves in water to give the green aquo complex [V(H₂O)₆]³⁺.

The compound is prepared by treating V₂O₅ in sulfuric acid with elemental sulfur:^[2]

V₂O₅ + S + 3 H₂SO₄ → V₂(SO₄)₃ + SO₂ + 3 H₂O

This transformation is a rare example of a reduction by elemental sulfur.

When heated in vacuum at or slightly below 410 °C, it decomposes into vanadyl sulfate (VOSO₄) and SO₂. Vanadium(III) sulfate is stable in dry air but upon exposure to moist air for several weeks forms a green hydrate form.

Vanadium(III) sulfate is a reducing agent.
