The present invention relates to a rubber composition for an engine mount of a commercial vehicle, which comprises, with respect to 100 wt% of a total rubber composition, 48 to 52 wt% of ethylene propylene diene M-class rubber (EPDM), 35.5 to 39.5 wt% of a carbon-based compound, and the remainder like organic additives and inorganic substances. The present invention provides the rubber composition for the engine mount of a commercial vehicle, wherein the content of EPDM to the carbon-based compound is 1.2 to 1.5. The present invention aims to provide the rubber composition for the engine mount of a commercial car, which has a vibration insulating property equal to a vibration insulating property of a rubber composition for an engine mount using natural rubber, and has improved rigidity and high temperature durability.
