Highlights of the talks given during the "QCD and Hadronic Final States" working-group sessions are summarised. The contributions included the latest measurements on QCD and final states from colliders experiments at TeVatron, HERA and LHC and new results from the NA48/2, NA62, BaBar, PHENIX and Belle experiments. The most recent theoretical developments were also presented; the recent developments on fixed-order QCD, resummation and Monte Carlo models were discussed.
