  Recent QCD results from ATLAS taken at 7 TeV center-of-mass energy using the
LHC are presented, including: dijet production, isolated photon production,
isolated photon production associated with jets, jet shapes in top-quark pair
events, the production cross-section of the phi(1020) meson, and underlying
event in jet events. Good agreement with theory predictions is seen, in
particular with those made by next-to-leading-order generators. These
measurements highlight the importance of precision QCD measurements for
improving state-of-the-art theoretical tools and searching for new physics.
