An X-ray pulsar jet associated with PSR 0355+54 was discovered from a ROSAT PSPC observation. The jet feature, a nearly linear diffuse enhancement in the direction opposite to the pulsar's proper motion with a length of about 12', is similar to the X-ray emitting trail of PSR 1929+10. Spectrum fitting in the 0.5 to 2.0 keV energy band gives a jet luminosity of 2.48±0.83×1024J/s, assuming that the column absorption and the distance are the same as those of the pulsar and a power-law photon index of α = -0.5. An average magnetic field of about 7.9×10-9T at the place of the X-ray jet could be derived if the electrons radiate in a uniform magnetic field in the emitting flow, and the typical electron energy is about 2.1×107MeV.
