Preliminary results on inclusive jet production in
proton-antiproton collisions at s**(1/2) = 1.96 TeV based on 1 fb-1 of CDF
Run II data are presented.  Measurements are performed using different jet
algorithms in a wide range of jet transverse momentum and jet rapi+dity.  The
measured cross sections are compared to next-to-leading order perturbative
QCD calculations.
