The invention relates to a 1,4-cyclohexanedicarboxylic acid hydrogenation catalyst, and aims to solve the problem of low yield during preparation of the 1,4-cyclohexanedimethanol by hydrogenation of 1,4-cyclohexanedicarboxylic acid in the prior art. According to the technical scheme, the 1,4-cyclohexanedicarboxylic acid hydrogenation catalyst adopted is prepared from a carrier, an active componentand a promotor, wherein the carrier is active carbon; the active component contains Ru; the promoter contains Zn. The 1,4-cyclohexanedicarboxylic acid hydrogenation catalyst can be applied to the industrial production of the 1,4-cyclohexanedimethanol.
