Disclosed is a roll driving system for a rolling mill. The roll driving system comprises hydraulic cylinders disposed in parallel between a rolling mill housing and a roll housing for supporting a backup roll and a work roll; load position sensors for detecting load positions of the hydraulic cylinders; means for executing a backward kinematic algorithm which calculates target load positions of the hydraulic cylinders when a target position instruction signal for degrees of freedom of roll movement is inputted from an upper control system, position controllers for controlling positions of the hydraulic cylinders in response to the target load positions inputted from the backward kinematic algorithm executing means; and means for executing a forward kinematic algorithm which calculates positions for the degrees of freedom of roll movement, based on the load positions detected by the load position sensors, and outputs resultant position signals to the upper control system.
