Provided is a novel method for producing an olefin by which an industrially practical method for obtaining an olefin with high selectivity by directly reacting a ketone with hydrogen in a single reaction step can be established. Particularly provided is a novel method for producing an olefin to obtain propylene with high selectivity by directly reacting acetone with hydrogen. In the method for producing an olefin, ketone is reacted with hydrogen at a reaction temperature ranging from 50 to 300 DEG C in the presence of a hydrogenation catalyst including Cu and a solid acid substance.
