Results in QCD physics at the Tevatron from the D0 and CDF
collaborations are presented, including results in jet production, photon
production, W/Z bosons plus jets, and heavy-flavor jets.  The importance of
these topi+cs in tuning Monte-Carlo simulations, constraining the parton
distribution functions, and measuring cross sections of QCD processes which
contribute significant backgrounds to searches for new and important physics
is discussed.
