  This contribution reports preliminary jet results in ppbar collisions at
sqrt(s)=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 rapidity
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.
