Actinium(III) oxide is a chemical compound containing the rare radioactive element actinium. It has the formula Ac₂O₃. It is similar to its corresponding lanthanum compound, lanthanum(III) oxide, and contains actinium in the oxidation state +3.^[1]^[2] Actinium oxide is not to be confused with Ac₂O (acetic anhydride), where Ac is an abbreviation for acetyl instead of the symbol of the element actinium.
