About two hundred stars within 50 pc from the sun, whose tangential velocity larger than 100km/sec, have been selected on the basis of their proper motions and trigonometric parallaxes. A list of them along with their photoelectric UBV data and spectral types is given. The criterion on the tangential velocity, v_t > 132km/sec, was adopted for selection of high-velocity stars. The H-R diagram of these nearby high-velocity stars resembles that of a globular cluster, with the turnoff around B-V ~ 0.35 and M_v ~ 4.0, and the subdwarfs among these high-velocity stars are fainter than the main-sequence stars of Hyades by the amount of 1.25^m +- 0.30^m in the region with B-V < 1.40 on the average.
