QCD AT THE LHC WITH ATLAS

The LHC will allow QCD studies to be performed at very high energy, including precision tests and measurements in an as yet unexplored kinematic region. A detailed understanding of QCD is important for almost all physics processes to be studied at the LHC, as the production mechanisms are mostly controlled by QCD. This contribution presents an overview of various measurements of QCD-related processes to be performed at the LHC, based mostly on final states containing high $p_T$ leptons, photons and jets.
