Data are presented on the J2000.0 positions and proper motions of 257 stars in the central 1.5 deg x 1.5 deg area of the Praesepe astrometric standard region. These data obtained with accuracies of 0.005-0.10 arcsec for the positions in each direction and 0.0002-0.006 arcsec/yr for the proper motions in each direction. The list includes stars for which proper motions were not given in the Russell (1976) catalog.
