The invention discloses a drawing die and a drawing system for a metal wire. The drawing die comprises a tapered inlet region, a lubricating region, a tapered compression region, a cylindrical sizing region and a tapered outlet region which are sequentially connected through a circular arc transition portion; and the angle of the taper angle of the die decreases gradually from the tapered inlet region to the compression region, and the angle of the taper angle of the compression region ranges from 5 degrees to 12 degrees. The drawing system comprises a pay-off device, a drawing box body, at least one supporting seat, a traction device and a take-up device. The supporting seats are obliquely arranged on the inner wall of the drawing box body. The drawing die is mounted in mounting holes of the supporting seats. When the metal wire passes the compression region of the drawing die, compared with a drawing die in the prior art, by the adoption of the drawing die and the drawing system, if the same metal wire compression rate and the small reduction of the area are reached, the required traction force provided by the traction device is minimum, the loss of the internal gold phase structure of the metal wire material is small, a die core is not destroyed, the service life of the drawing die is prolonged, and the surface of the drawn metal wire is smooth.
