The invention provides a method for preparing 3,3,5-trimethyl-cyclohexanone by selectively hydrogenating isophorone (namely 3,3,5-trimethyl-2- cyclohexenone). The method comprises the step of selectively hydrogenating to reduce isophorone into 3,3,5-trimethyl-cyclohexanone through combined use of supported Pd or Pt catalyst and co-catalyst under the condition that the reaction temperature is 20-100 DEG C. The method is remarkably characterized in that the byproduct 3,3,5-trimethyl-cyclohexanol is inhibited by adding the preferred cocatalyst, so that the product 3,3,5-trimethyl-cyclohexanone has relatively high selectivity and yield on the premise of realizing the high conversion rate of the isophorone under a relatively mild condition.
