Provided that a method for inexpensively producing optically active alpha-ionone with a high yield and a high asymmetric yield and with good workability in a short process, and a perfume composition comprising the optically active alpha-ionone obtained by the aforementioned method. A method for producing optically active alpha-ionone, comprising allowing alpha-ionone as a mixture of optical isomers to react with an esterification agent, and hydrolyzing the obtained alpha-ionone enol ester; a method for producing optically active alpha-ionone comprising subjecting alpha-ionone as a mixture of optical isomers to an asymmetric reduction, allowing the obtained optically active alpha-ionol to react with an esterification agent to give an optically active alpha-ionol ester, hydrolyzing the obtained optically active alpha-ionol ester after purification as necessary, and then oxidizing the obtained optically active alpha-ionol; and a perfume composition comprising thus obtained optically active alpha-ionone.
