Results on recent QCD measurements performed at the Tevatron ppbar Collider
at sqrt{s} = 1.96 TeV are here reported. The inclusive jet and dijet mass cross
sections are compared to NLO pQCD calculations and to Run I results. The
production rates and kinematic properties of W + jets production processes are
compared to ``enhanced'' LO theoretical predictions. Non-perturbative ``soft''
interactions leading to the underlying event are studied and compared to QCD
Monte Carlo phenomenological models.Comment: Presented at 18th Les Rencontres De Physique De La Vallee D'Aoste:
