A workpiece position/posture calculation system which is able to efficiently calculate a position and posture of a workpiece utilizing 3D matching. The workpiece position/posture calculation system includes a workpiece position/posture calculation part comparing measurement data including 3D position information of a workpiece obtained by a 3D measuring device against a 3D model of the workpiece to calculate the position and posture of the workpiece. Further, the workpiece position/posture calculation system further includes a measurement data excluding part excluding part of the measurement data to be used in subsequent calculation by the workpiece position/posture calculation part based on the calculated position and posture of the workpiece.
