We present results on inclusive jet production in
proton-antiproton collisions at s**(1/2) = 1.96 TeV. The measurements are
based on 1.0 fb-1 of CDF Run II data and were carried out for jets in five
different jet rapi+dity regions up to |Y| = 2.1. Both the midpoint cone
based algorithm and k_T algorithm were investigated to reconstruct the jets.
The results are compared to next-to-leading order perturbative QCD
predictions.
