Provided is a hydrogenation method that with respect to a hydrocarbon mixture containing 1,3-butadiene and vinylacetylene, enables hydrogenation of vinylacetylene while inhibiting reduction of 1,3-butadiene concentration. The hydrogenation method is a method of hydrogenating a hydrocarbon mixture containing 1,3-butadiene and vinylacetylene that includes a step of bringing the hydrocarbon mixture and a hydrogenation catalyst into contact in the presence of hydrogen to hydrogenate at least vinylacetylene. The hydrocarbon mixture contains 1 mass % or more of vinylacetylene. The hydrogenation catalyst includes palladium and has a CO adsorption amount of 0.5 cm3/g or less.
