QCD Studies at HERA
  I present a small selection of the many QCD studies that have been performed at HERA. I concentrate on results that have been made available in the past year. Results are presented on the QCD description of the parton density functions, determinations of alpha_S, jets and heavy flavour production. Where possible comparisons are made with next to leading order (NLO) QCD predictions. The neutral and charged current cross sections at very high Q^2 are also discussed.
