  Hard QCD results in proton-proton collisions at sqrt(s) = 7 TeV with jets
from data recorded up to the end of 2010 by the CMS and ATLAS experiments at
the LHC are reported. Inclusive jet and di-jet cross section measurements as
well as observables sensitive to multi-jet activity are shown and compared to
simulations based on leading log parton showers as well as NLO QCD predictions.
Novel approaches to identify highly boosted massive final states by exploiting
the jet substructure are tested on the dominant QCD background.
