The invention provides a selective hydrogenation method for alpha-methyl styrene, which comprises: alpha-methyl styrene-containing raw material circulation pass through nickel-based catalyst and palladium-based catalyst with hydrogen in sequence, after one-step hydrogenation, the alpha-methyl styrene is converted into isobutylbenzene. Optimally, nickel-based catalyst and palladium-based catalyst are contacted directly. According to the hydrogenation method provided by the invention, the reaction material circulation continuously passes through different catalysts, thereby realizing one-step hydrogenation, and simplifying reaction equipment and reaction technology, and saving cost. In addition, according to the invention, the hydrogenation reaction condition is mild, and the catalyst activity is high, and the hydrogenation conversion rate and hydrogenation selectivity are high.
