Zirconium selenate is an inorganic compound with the chemical formula Zr(SeO₄)₂. Its tetrahydrate can be obtained by the reaction of selenic acid and a saturated aqueous solution of zirconium oxychloride octahydrate (or zirconium hydroxide). The tetrahydrate belongs to the orthorhombic crystal system and is isostructural with Zr(SO₄)₂·4H₂O. It loses water when heated and becomes anhydrous at 220-230 °C. It reacts with potassium fluoride to obtain K₂Zr(SeO₄)₂F₂·3H₂O.
