Gold(III) oxide (Au2O3) is the most stable oxide of gold. It is a red-brown, thermally unstable solid that decomposes at 160 °C. The hydrated form is weakly acidic and dissolves in concentrated alkali to form salts that are believed to contain the Au(OH)4- ion.

Anhydrous Au2O3 can be prepared by heating amorphous hydrated gold(III) oxide with perchloric acid and an alkali metal perchlorate in a sealed quartz tube at a temperature of around 250 °C and a pressure of around 30 MPa.
