QCD Physics at the Tevatron
  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.
