This contribution reports preliminary jet results in p anti-p
collisions at s**(1/2) = 1.96 TeV from the CDF and D0 experiments.  The jet
inclusive cross section, measured using both the Midpoint and the K_T jet
clustering algorithm, is compared to next-to-leading order QCD prediction in
different rapi+dity regions.  The b-jet inclusive cross section measured
exploiting the long lifetime and large mass of B hadrons is presented and
compared to QCD prediction.  A complementary measurement, using the large
branching fraction of B hadrons into muons, is also described.  The
measurement of two-particle momentum correlation in jets is presented and
compared to predictions.
