El óxido de actinio(III) es un compuesto químico inorganico que contiene el raro elemento radiactivo actinio. Tiene la fórmula Ac2O3.

Es similar a su correspondiente compuesto de lantano, el óxido de lantano(III), y contiene actinio en el estado de oxidación +3.[2]​[3]​ El óxido de actinio no debe confundirse con Ac2O (anhídrido acético), donde Ac es una abreviatura de acetilo en lugar del símbolo del elemento actinio.
