  Inclusive multi-jet production is studied using the ATLAS detector for
proton-proton collisions with a center-of-mass energy of 7 TeV. The data sample
corresponds to an integrated luminosity of 2.43 pb^-1, using the first
proton-proton data collected by the ATLAS detector in 2010. Results on
multi-jet cross sections are presented and compared to both leading-order plus
parton-shower Monte Carlo predictions and next-to-leading-order QCD
calculations.
