The present invention relates to a clutch control method of a hybrid vehicle, including: an entry condition determining step of determining whether a controller is in a shift state during regenerative braking; an error calculating step of calculating a torque error by subtracting an observer torque which is a clutch transmission torque calculated by a clutch torque estimator that receives a transmission input torque and a motor speed as inputs, from a map torque, which is the clutch transmission torque calculated from the map of the clutch transmission torque for an already learned clutch actuator stroke, in the case of the shift state during regenerative braking; a correction step of a controller correcting a map of the clutch transmission torque for the clutch actuator stroke by using the torque error calculated in the error calculating step; and a clutch controlling step of the controller using the map corrected in the correction step and controlling the clutch. Accordingly, the present invention is able to prevent deceleration and shifting shock by more precise control of clutch transmission torque during regenerative braking and shifting.
