PROBLEM TO BE SOLVED: To provide an engine vibration control system certainly controlling vibration of an engine in order to improve the controllability and stability of a vehicle. SOLUTION: This engine vibration control system 10 includes: a plurality of acceleration sensors 4a, 4b fixed on the engine 1 and detecting acceleration in a rolling direction; a plurality of active control mounts (ACMs) 3a, 3b supporting the engine and controlling vibration of the engine; and a control section 11 controlling vibration control force of the ACMs in real time based on acceleration signals from the acceleration sensors. The acceleration sensors are arranged symmetrically with respect to the axis ST of the drive shaft of the engine. The control section is provided with a high-speed arithmetic unit calculating the control signals of the ACMs based on an immobilized feedback filter matrix and a difference between the signals from the pair of acceleration sensors. The feedback filter matrix consists of a constant calculated based on the difference between the acceleration signals detected by the pair of acceleration sensors when the ACMs are operated to shake the engine.
