Zinc titanate, also known as zinc titanium oxide, is an inorganic compound existing in three major forms: ZnTiO₃ (ZnO-TiO₂), Zn₂TiO₄ (2ZnO-TiO₂) and Zn₂Ti₃O₈ (2ZnO-3TiO₂). It is used as a regenerable catalyst, a pigment and a sorbent of sulfur compounds at elevated temperatures. It is a white powder that is insoluble in water.

The ZnTiO₃, Zn₂TiO₄ and Zn₂Ti₃O₈ forms crystallize in hexagonal, cubic (inverse spinel) and cubic structures, respectively. They can be produced by heating a mixture of ZnO and TiO₂ powders or processing it with a ball mill. Zn₂Ti₃O₈ forms at lowest temperatures, followed by ZnTiO₃ and then Zn₂TiO₄; the last phase dominates at temperatures above 1000 °C.
