A study of the polarization of hyperons produced in inelastic pN reactions induced by the 450 GeV proton beam from the CERN SPS has been performed with the NA48 detector. The hyperons were detected at a fixed angle of 4.2 mrad in the momentum range from 50 GeV/c to 200 GeV/c. The polarization changes from to for a transverse momentum range of the between 0.28 GeV/c and 0.86 GeV/c. The polarization is consistent with zero.
