A concentricity measurement tool of the present invention comprises a measurement tool body, a driving wheel installation shaft, a driven wheel installation shaft, a driving wheel, a driven wheel, an installing base, a clamping wheel installation shaft, a clamping wheel and guide shaft. The driving wheel installation shaft and the driven wheel installation shaft are both arranged on the measurement tool body, and the driving wheel and the driven wheel are fixed on the driving wheel installation shaft and the driven wheel installation shaft respectively and are arranged relatively up and down. The clamping wheel installation shaft is arranged on the installing base, the clamping wheel is fixed on the clamping wheel installation shaft, and the guide shaft penetrates the installing base and is connected with the measurement tool body. A spring sleeves the guide shaft, one end of the spring abut against the measurement tool body, and the other end abuts against the installing base. The peripheral surface of the clamping wheel is contacted with the peripheral surface of the driving wheel and the peripheral surface of the driven wheel tightly and separately. The concentricity measurement tool of the present invention can measure the single reference concentricity and the radial runout of the stepped shaft workpieces rapidly, is high in measurement precision and measurement efficiency, and is especially suitable for the on-site measurement of the mass workpieces.
